Q. What are the basic operations of MOSFET?
The gate to source voltage is set to zero volts by the direct connection from one terminal to the other,and a voltage Vds is applied the drain to source terminals.The result is the attraction for the positive potential on at the drain by the free electrons if the n-channel and a current similar to that established through the channel of the JFET.In fact the resulting current with Vgs=0V continues to be labeled Idss.
Vgs has been set at a negative voltage such as -1V.The negative potential at the gate will tend to pressure electron towards the p-type substrate and attract holes from p-type substrate .Depending on the negative bias established by Vgs ,a level of recombination between electrons and holes will occur that will reduce the number of free electron in the n channel available for conduction .The more negative the bias the higher rate of recombination .The resulting value of drain current is therefore reduced with increasing negative bias for Vgs.
Digital Transmission on Fading Multipath Channels We have discussed thus far digital modulation and demodulation methods for the transmission of information over two types of c
Q. In the circuit shown in Figure with an ideal op amp, find v o as a function of v a and v b .
Hai.. i have been given a open loop transfer function to draw a bode plot with a particular K value and they asked me to find the value of K for which the phase margin becomes 45d
With a maximum excess delay of and a chip duration of , the multipath components fall in delay bins. This means that we experience leakage of energy between chips and the channel i
