What is channel length modulation in MOSFET?

Channel length modulation (CLM) is a shortening of the length of the inverted channelregion 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.

Shortening of lenght of the inverted channel region with increase in drain bias for large drain biases due to which current increases with drain bias and output resistance decreases is called channel length modulation in MOSFET.
