WebOct 25, 2024 · The channel then gets "pinched" and the charge concentration close to the drain is nullified. The boundary separating the linear and saturated zones is known as channel pinch-off. The channel-length modulation effect previously stated occurs as VDS rises because the pinch point shifts and the channel's effective length decreases.[4] Channel length modulation (CLM) is an effect in field effect transistors, a shortening of the length of the inverted channel region with increase in drain bias for large drain biases. The result of CLM is an increase in current with drain bias and a reduction of output resistance. It is one of several short-channel effects in MOSFET scaling. It also causes distortion in JFET amplifiers. long term home loans
