WebAnswer (1 of 2): What is meant by the early voltage of a reflection transistor in a MOSFET current mirror? You mean the Early Effect, or as it is more properly called in MOSFETs, channel length modulation? MOSFET Channel-Length Modulation In a simple two transistor current mirror, it relies on... WebOct 20, 2016 · Here, the total output resistance is calculated when the Early voltage is completely unspecified and neglected (I suppose it's zero). How has this been done? The formula for terminal output resistance (Ro) for BJT Amplifiers is (Va + Vce)/Ic where Va is the Early voltage, Vce and the collector-emitter voltage and Ic is the collector current.
