Abstract
A folded-cascode amplifier conventionally comprises an 'input' transistor of a first conductivity type receiving input signals at its base electrode, an 'output' transistor of a second conductivity type, complementary to the first, connected in common-base amplifier configuration with its base electrode connected to receive fixed bias potential, and a current source supplying the combined 'input' transistor collector current and 'output' transistor emitter current to an interconnection between the 'input' transistor collector electrode and 'output' transistor emitter electrode. In the folded-cascode amplifiers herein disclosed the base electrode of the 'output' transistor has the input-signal-responsive emitter potential of the 'input' transistor applied to it.
