For example let's say that we have a current mirror. How do i know what is the
best choice of nf for both transistors? I am asking this because i have
noticed through monte carlo analysis that keeping the ratio of Wtotal (so the
current ratio also constant!) constant and change only the nf, the mismatch of ΔID/ID is being changed!Also i have noticed that decreasing nf mismatch sometimes increases and sometimes decreases! Why this happen as the operation region and point is constant and same?
Thanks!
