what is Channel length modulation?

Answer Posted / arjun

Ideally, In Saturation region, Ids is independent of Vds.
But the reverse biased junction between the drain and body forms a depletion region of width Ld which increases with Vds(= Vdb).

This increase in the depletion region width will decrease the size of the channel.
L(eff) = L(actual) - Ld.
With the increase in Vds, The effective channel length decreases which means higher current.
This is important because it reduces the gain of the amplifier
