About this document
Understanding Channel Length Modulation by Fariha Jannat is a document available to read on EtoBox.
Channel Length Modulation is a second order effect that occurs in MOSFETs when the drain voltage exceeds the overdrive voltage. The channel takes on a tapered shape, pinching off near the drain. This effectively reduces the channel length and allows the pinch off point to move toward the source. As a result, the drain current increases with drain voltage in saturation, and the MOSFET exhibits a finite output resistance.
