Early effect in common base configuration

Author: fyld

August undefined, 2024

WebIn CB configuration a variation of the base-collector voltage results in a variation of the quasi- neutral width in the base. The gradient of the minority-carrier density in the base therefore changes, yielding an increased collector current as the collector-base current is increased. This effect is referred to as the Early effect.

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).
