Pinch off Voltage

At $V_{GS}=0$, in response to a small applied voltage $V_{DS}$, the n-type bar acts as a simple semiconductor resistor and the current $I_D$ increases linearly with $V_{DS}$. As $V_{DS}$ increases, the voltage drop along the channel also increases. This increase in voltage drop increases the reverse bias …
