High Speed and Low Pedestal Error Bootstrapped CMOS Sample and Hold CircuitIJECEIAES
A new high speed, low pedestal error bootstrapped CMOS sample and hold (S/H) circuit is proposed for high speed analog-to-digital converter (ADC). The proposed circuit is made up of CMOS transmission gate (TG) switch and two new bootstrap circuits for each transistor in TG switch. Both TG switch and bootstrap circuits are used to decrease channel charge injection and on-resistance input signal dependency. In result, distortion can be reduced. The decrease of channel charge injection input signal dependency also makes the minimizing of pedestal error by adjusting the width of NMOS and PMOS of TG switch possible. The performance of the proposed circuit was evaluated using HSPICE 0.18-m CMOS process. For 50 MHz sinusoidal 1 V peak-to-peak differential input signal with a 1 GHz sampling clock, the proposed circuit achieves 2.75 mV maximum pedestal error, 0.542 mW power consumption, 90.87 dB SNR, 73.50 SINAD which is equal to 11.92 bits ENOB, -73.58 dB THD, and 73.95 dB SFDR.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Sample and hold instru
1.
2. Sample-and-hold (S/H) is an important analog
building block with many applications,
including analog-to-digital converters (ADCs)
and switched-capacitor filters.
The function of the S/H circuit is to sample an
analog input signal and hold this value over a
certain length of time for subsequent
processing.
3. The simplest S/H circuit in MOS technology is
shown in Figure 1, where Vin is the input
signal, M1 is an MOS transistor operating as
the sampling switch, Ch or Cs is the hold
capacitor,ck is the clock signal, and Vout is the
resulting sample-and-hold output signal.
4. Switched op-amp based sample and hold circuit Switched op-
amp based sample and hold circuit
5. During sample mode, the SOP behaves just like
a regular op-amp, in which the value of the
output follows the value of the input.
During hold mode, the MOS transistors at the
output node of the SOP are turned off while
they are still operating in saturation, thus
preventing any channel charge from flowing
into the output of the SOP.
In addition, the SOP is shut off and its output is
held at high impedance, allowing the charge on
Ch to be preserved throughout the hold mode.
6. On the other hand, the output buffer of this
S/H circuit is always operational during
sample and hold mode and is always
providing the voltage on Ch to the output of
the S/H circuit.
7. The sample and hold circuits are essentially
used in linear systems.
In some kinds of analog-to-digital converters,
the input is often compared to a voltage
generated internally from a digital to analog
converter D-A-C.
The circuit tries a series of values and stops
converting once the voltages are "the same"
within some defined error margin.
8. Pre-digital electronic cruise control on automobiles would use
a "sample and hold" circuit to "remember“.
the current speed (a voltage proportional to speed generated
from the speedometer)
so that the current automobile speed could be compared to the
set point to determine
whether the throttle should be opened wider or closed down a bit.
9. If the input value was permitted to change during
this comparison process, the resulting conversion
would be inaccurate and possibly completely
unrelated to the true input value. Such successive
approximation converters will often incorporate
internal sample and hold circuitry.
In addition, sample and hold circuits are often
used when multiple samples need to be measured
at the same time. Each value is sampled and held,
using a common sample clock.
10. In order that the input voltage is held constant
for all practical purposes, it is essential that the
capacitor have very low leakage, and that it not
be loaded to any significant degree which calls
for a very high input impedance.
A true sample and hold circuit is connected to
the buffer for a short period of time; a track and
hold circuit is designed to track input
continuously.
11. Sample-and-hold (S/H) is an important analog
building block that has many applications.
The simplest S/H circuit can be constructed using
only one MOS transistor and one hold capacitor.
However, due to the limitations of the MOS
transistor switches, errors due to charge injection
and clock feed through restrict the performance of
S/H circuits.
As a result, different S/H techniques and
architectures are developed with the intention to
reduce or eliminate these errors.
