Channel Length Modulation

The inversion layer charge Q I represents the total mobile electron charge on the surface and its expression at the source end of the channel is: Q I at x=0 =-C ox (V GS -V T0 ) and the inversion layer charge at the drain end of the channel is expressed as: Q I at x=L =-C ox (V GS -V T0 -V DS )
