This project shows the design of a three stage CMOS
operational amplifier including a bias network in 0.35um CMOS
process.
The design specifications for this op-amp are:
1. AVo (DC Gain) > 60 dB
2. GBW > 1 MHz
3. PM (Phase Margin) > 45 degree
4. CL = 30 pF
5. PD < 2 mW
6. PSRR > 60 dB
Structure
The input stage is made up of the source-coupled pair transistors
(M1-M2) and the folded mirror transistors (M3-M4). The second
stage is a PMOS (M7) common source gain stage and the last
stage is a class AB push-pull output stage. Common source
transistors M11 and M12 provide a rail-to-rail output swing and
diode connected transistors (M8-M9) are used to bias the output
source follower transistors at class-AB. A Miller compensation
capacitor is added to the gain stage to ensure the stable
operation of the amplifier in closed loop. Bias network transistors
(M13-M15) supplies a bias current of 0.12 mA. The circuit has a
dual power supply of +2.5 and -2.5 volts.

As modern technology is spreading fast, it is very important to design low power, high performance, fast responding SRAM(Static Random Access Memory) since they are critical component in high performance processors. In this paper we discuss about the noise effect of different SRAM circuits during read operation which hinders the stability of the SRAM cell. This paper also represents a modified 6T SRAM cell which increases the cell stability without increasing transistor count.

This paper presents the design and performance comparison of a two stage operational amplifier topology using CMOS and BiCMOS technology. This conventional op amp circuit was designed by using RF model of BSIM3V3 in 0.6 μm CMOS technology and 0.35 μm BiCMOS technology. Both the op amp circuits were designed and simulated, analyzed and performance parameters are compared. The performance parameters such as gain, phase margin, CMRR, PSRR, power consumption etc achieved are compared. Finally, we conclude the suitability of CMOS technology over BiCMOS technology for low power RF design.

- In such transceiver system, we used power amplifier stage in transmitter section and polyphase filter (PPF) in local oscillator (LO) section - Less linearity of power amplifier causes higher order intermodulation and consequently destroys orthogonality between subcarriers in OFDM signals. - Phase error in quadrature LO signal causes crosstalk between I and Q signals and results unavoidable demodulation errors.

A method is presented in this paper for the design of a high frequency CMOS operational amplifier (OpAmp) which operates at 3V power supply using tsmc 0.18 micron CMOS technology. The OPAMP designed is a two-stage CMOS OPAMP followed by an output buffer. This Operational Transconductance Amplifier (OTA) employs a Miller capacitor and is compensated with a current buffer compensation technique. The unique behaviour of the MOS transistors in saturation region not only allows a designer to work at a low voltage, but also at a high frequency. Designing of two-stage op-amps is a multi-dimensional-optimization problem where optimization of one or more parameters may easily result into degradation of others. The OPAMP is designed to exhibit a unity gain frequency of 2.02GHz and exhibits a gain of 49.02dB with a 60.50 phase margin. As compared to the conventional approach, the proposed compensation method results in a higher unity gain frequency under the same load condition. Design has been carried out in Tanner tools. Simulation results are verified using S-edit and W-edit.

This paper presents a new topology to implement MOS current mod logic (MCML) tri-state buffers. In Mos current mode logic (MCML) current section is improves the performance and maintains low power of the circuit. MCML circuits contains true differential operation by which provides the feature of low noise level generation and static power dissipation. So the amount of current drawn from the power supply does not depends on the switching activity. Due to this MOS current mode logic (MCML) circuits have been useful for developing analog and mixed signal IC’s. The implementing of MCML D-flip flop and Frequency divider done by using MCML D-latches. The proposed MCML D-latch consumes less power as it makes use of low power tri-state buffers. Which promotes power saving due to reduction in the overall current flow in the proposed D flip flop topology is verified though Cadence GPDK-180nM CMOS technology parameters.

In this paper, a new adaptive biased low voltage cascode current mirror with high input/output swing is presented. This advantage is achieved using a self-biasing transistor and compensation resistor. The new structure profits from better input dynamic range and lower supply voltage without frequency response limitation and increasing input impedance. Also, the proposed current mirror is incorporated in folded cascode amplifier in order to enhance its phase-margin. The simulation results in 0.18 μm CMOS technology confirm the theoretical analysis and exhibits 478μA linear input/output current swing and a phase-margin enhancement of 12o for the proposed current mirror and amplifier compared to the conventional circuits, respectively

A qualitative analysis of different parameters such as Phase noise, Slew rate and tranconductance by using power gating reduction technique is presented. The circuit achieves the large driving capability by employing simple comparators to sense the transients of the input to turn on the output stages, which are statically off in the stable state. The effect of the different number of transistors and their topologies on the phase noise and Slew rate is analyzed. Good agreement between qualitative and quantitative measurements is observed. Scope of reducing of Noise and avoidance of Leakage due to various sources is discussed.

“HOSTEL MANAGEMENT SYSTEM” is a software developed for managing various activities in the hostel. For the past few years the number of educational institutions are increasing rapidly. Thereby the number of hostels are also increasing for the accommodation of the students studying in this institution. And hence there is a lot of strain on the person who are running the hostel and software’s are not usually used in this context. This particular project deals with the problems on managing a hostel and avoids the problems which occur when carried manually.

The project Hospital Management system includes registration of patients, storing their details into the system, and also computerized billing in the pharmacy, and labs. The software has the facility to give a unique id for every patient and stores the details of every patient and the staff automatically. It includes a search facility to know the current status of each room. User can search availability of a doctor and the details of a patient using the id. The Hospital Management System can be entered using a username and password. It is accessible either by an administrator or receptionist. Only they can add data into the database. The data can be retrieved easily. The interface is very user-friendly. The data are well protected for personal use and makes the data processing very fast. Hospital Management System is powerful, flexible, and easy to use and is designed and developed to deliver real conceivable benefits to hospitals. Hospital Management System is designed for multispecialty hospitals, to cover a wide range of hospital administration and management processes. It is an integrated end-to-end Hospital Management System that provides relevant information across the hospital to support effective decision making for patient care, hospital administration and critical financial accounting, in a seamless flow. Hospital Management System is a software product suite designed to improve the quality and management of hospital management in the areas of clinical process analysis and activity-based costing.

3 stage CMOS Amplifier

1. CMOS LNA Hamid Kiabi This project shows the design of a three stage CMOS operational amplifier including a bias network in 0.35um CMOS process. The design specifications for this op-amp are: 1. AVo (DC Gain) > 60 dB 2. GBW > 1 MHz 3. PM (Phase Margin) > 45 degree 4. CL = 30 pF 5. PD < 2 mW 6. PSRR > 60 dB Structure The input stage is made up of the source-coupled pair transistors (M1-M2) and the folded mirror transistors (M3-M4). The second stage is a PMOS (M7) common source gain stage and the last stage is a class AB push-pull output stage. Common source transistors M11 and M12 provide a rail-to-rail output swing and diode connected transistors (M8-M9) are used to bias the output source follower transistors at class-AB. A Miller compensation capacitor is added to the gain stage to ensure the stable operation of the amplifier in closed loop. Bias network transistors (M13-M15) supplies a bias current of 0.12 mA. The circuit has a dual power supply of +2.5 and -2.5 volts.
