  • Abstract
    The letter describes the design of a single-stage, double cascode amplifier for GaAs switch-capacitor filters. The amplifier achieves a voltage gain of 60 dB assuming a realistic low-gain model for the N-channel GaAs DFETs employed. The need for compensation is avoided using a single-stage architecture, and a push-pull output stage minimises power consumption and chip area.
