This improvement can be explained with an understanding of the early effect as shown in the video by w2aew. It provides a much more accurate input to output current gain. Current mirror circuits are very useful especially within integrated circuits.
Vo characteristic for ii 1 ma and vcc 10 v.
We note that q3 carries the same current as q2 because they are in series and q1 in turn mirrors the current of q2 so the left and right halves of the circuit carry identical currents. Figure 11 9 the wilson current mirror. How the wilson current mirror works at first glance the current mirror circuit shown to the right would seem to be backwards. The circuit is named after george r.
