Description : With the help of N-channel JFET describe the effect of input voltage VGS on output current ID.

Last Answer : Working of N channel FET: * When a voltage is applied between the drain and source with a DC supply (VDD), the electrons flows from source to drain through narrow channel ... where the channel gets completely blocked and the drain current becomes zero is called pinch- off voltage. 

Description : Explain N-channel J-FET with its transfer characteristics.

Last Answer : Working of Channel JFET: Working: 1. The application of negative gate voltage and positive drain voltage with respect to source, reverse biases the gate- source junction of an N-channel JFET. 2. When a ... symbol VP or VGS(OFF) . The value of VP is negative for N-channel JFET. 

Description : Differentiate between N-channel and P-channel J-FET.

Last Answer : N-Channel JFET P-Channel JFET 1.The current conduction takes place due to electrons 1.The current conduction takes place due to holes. 2.Its switching speed and cut off ... It is most widely used in circuit applications 5.It is comparatively less used in circuit applications

Description : Describe the operation of N channel enhancement type MOSFET with diagram.

Last Answer : As its name indicates, this MOSFET operates only in the enhancement mode and has no depletion mode. It operates with large positive gate voltage only. It does not conduct when the ... of charge carriers attracted to the positive gate. Thus drain current is controlled by the gate potential.

Description : Describe operation of N-channel JFET

Last Answer : Operation of N-channel JFET  1) When VGS = 0 volt: When a voltage is applied between the drain and source with a DC supply voltage VDD with VGS = 0 V, the electrons flow from source ... to zero. The gate to source voltage at which current reduces to zero is called as pinch-off voltage.
