transistor size
We usually calculate transistor sizes as W/L. But in real design I saw 100/2, 100/3 when the technology is 1um. Why using sizes larger than the minimum length? And how to decide that?
Larger transistors may can reduce noise. But when we start a design, how can we generate sizes like 100/2 instead of 50/1?
