WebSep 14, 2012 · The problem is however, that the Early effect causes beta (of the output transistor) to increase as Vce increases, due to base narrowing. In the Wilson mirror this is countered by allowing the base matched pair Q1/Q2 to operate at similar Vce levels and buffering the output through Q3 (so as to allow for voltage swings at the Q3 collector). WebSep 11, 2012 · yungman. Yes, the variation of Ic vs. Vce in a common emitter configuration is caused by the Early effect. Notice that Early is capitalized, because it was named after James Early. In a common base configuration, one sees flat lines on the Ic vs. Vcb curve. Notice that the x-axis of the CE is Vce and on the CB is Vcb.
