Pinch off voltage, Electrical Engineering

Pinch off Voltage:

The current in N-JFET because of a small voltage VDS is described by:

IDSS = (2a) W/L (qNdμnVDS)

In which2a = channel thickness

  1. W stands for width
  2. L stands for length
  3. q stands for electronic charge = 1.6 x 10-19 C
  4. μn stands for electron mobility
  5. Nd stands for n type doping concentration

In the saturation region:

IDS =IDSS [1- VGS /VP] 2

In the linear region

Or (in terms of IDSS):

ID = 2IDSS/V2P (VGS - VP - VDS/2) VDS
