Regards, David Collin Wells over 11 years ago in reply to David Musoke TI__Guru 60025 points Hi David, WebThe ratio of source current to mirror current is specified by n, the “Current Mirror Ratio”. This ratio is defined for conditions where both source and mirror terminals are held at the same potential. Since n is on the order of 1000:1, load current is approximately equal to source current, and the current mirror ratio also describes the ...
