ABSTRACT:
A folded-cascode amplifier arrangement includes first and second transistors of complementary conductivity type and a constant current generator for supplying quiescent current thereto. Signal current flowing in the first transistor is coupled to the second transistor through current steering at the interconnection between their main conduction paths. The load means for the second transistor includes a cascode-connected third transistor for supplying load current thereto, which third transistor substantially increases the resistance of the load for correspondingly increasing the voltage gain of the amplifier arrangement. The amplifier voltage gain transfer function exhibits a frequency response dominated by a single pole.
