Question

The equivalent w/l of two mos transistors with aspect ratio (w1/l) and (w2/l) respective connected in parallel is

Answer 1

When transistors are connected in series their equivalent resistance is added up whereas the equivalent W/l ratio becomes 1/n times where n is the number of transistors connected.

When two transistors of W1/l and W2/l ratio are connected in parallel, then the equivalent W/l ratio is added up to become (W1+W2)/l.
