Analytical Modeling of Tunneling Field Effect Transistor (TFET)Abu Obayda
Tunneling Field-Effect Transistor (TFET) has emerged as an alternative for conventional CMOS by enabling the supply voltage, VDD, scaling in ultra-low power, energy efficient computing, due to its sub-60 mV/decade sub-threshold slope (SS). Given its unique device characteristics such as the asymmetrical source/drain design induced unidirectional conduction, enhanced on-state Miller capacitance effect and steep switching at low voltages, TFET based circuit design requires strong interactions between the device-level and the circuit-level to explore the performance benefits, with certain modifications of the conventional CMOS circuits to achieve the functionality and optimal energy efficiency. Because TFET operates at low supply voltage range (VDD<0.5V) to outperform CMOS, reliability issues can have profound impact on the circuit design from the practical application perspective. In this thesis report, we have analyzed the drain current characteristics of TFET with respect channel length. From our simulation result, it is observed that the drain current is minimum with respect to increasing channel length for Si and the drain current decreases for all the materials when the channel length is increased and after normalization lowest value of drain current is got for 10nm channel length.
This presentation is for beginners of electronics. This will give you a brief about all the important basic building blocks of electronics and hence will be helpful in creating a good foundation.
Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

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.

2. Metal Oxide Field Effect Transistor
(MOSFET)
INTRODUCTION:
Metal Oxide in the name MOSFET stands for the
thin insulating layer of silicon oxide layer in the
region between metal and semiconductor.
The term field effect stands for the fact that the
operation of the device mainly depends on the
electric field applied between its terminals called
Gate and source analogous to the base and collector
in transistor to control the current through it.
3. TYPES OF MOSFET
Enhancement type MOSFET
N-channel Enhancement type
P-channel Enhancement type
Depletion type MOSFET
N-channel Depletion type
P-channel Depletion type
4. APPLICATIONS OF MOSFET
The MOSFET as a Switch
We saw previously, that the N-channel,
Enhancement-mode MOSFET (e-MOSFET)
operates using a positive input voltage and has
an extremely high input resistance (almost
infinite) making it possible to interface with
nearly any logic gate or driver capable of
producing a positive output. Also, due to this
very high input (Gate) resistance we can parallel
together many different MOSFETs until we
achieve the current handling limit required.
6. JFET(JUNCTION FIELD
EFFECT TRANSISTOR)
ITNRODUCTION:
A transistor is a linear semiconductor device that controls
current with the application of a lower-power electrical
signal. Transistors may be roughly grouped into two
major divisions: bipolar and field-effect. In the last
chapter we studied bipolar transistors, which utilize a
small current to control a large current. In this chapter,
we'll introduce the general concept of the field-effect
transistor -- a device utilizing a smallvoltage to control
current -- and then focus on one particular type:
the junction field-effect transistor. In the next chapter
we'll explore another type of field-effect transistor,
the insulated gate variety.
7.
8. APPLICATIONS OF JFET
The transistor as switch:
Like its bipolar cousin, the field-effect transistor may
be used as an on/off switch controlling electrical
power to a load. Let's begin our investigation of the
JFET as a switch with our familiar switch/lamp
circuit:
9. ADVANTAGES AND DISADVANTAGES OF
(JFET)
1.Its operation depends upon the flow of majority carriers only, it is,
therefore, a unipolar (one type of carrier) device. On the other hand
in an ordinary transistor both majority and minority carriers take
part in conduction and, therefore, ordinary transistor is sometimes
called the bipolar transistor. The vacuum tube is another example of
a unipolar device.’
2.It is simpler to fabricate, smaller in size, rugged in construction
and has longer life and higher efficiency. Simpler to fabricate in IC
form and space requirement is also lesser.
The main drawback of JFET is
1. Its relative small gain-bandwidth product in comparison with that
of a conventional transistor.
2. Greater susceptibility to damage in its handling.
3. JFET has low voltage gains because of small transconductance .
4. Costlier when compared to BJT’s.
10. Characteristics of JFETS
There are two types of static characteristics viz
(1) Output or drain characteristic and
(2) Transfer characteristic.
1. Output or Drain Characteristic. The curve drawn between drain
current Ip and drain-source voltage VDS with gate-to source voltage
VGS as the parameter is called the drain or output
characteristic. This characteristic is analogous to collector
characteristic of a BJT:
(a) Drain Characteristic With Shorted-Gate. The circuit diagram for
determining the drain characteristic with shorted-gate for an N-
channel JFET is given in figure. and the drain characteristic with
shorted-gate is shown in another figure.
