Realisation of high frequency GaAs switched capacitor filters using insulated gate switches

The design and evaluation of a first-order switched capacitor (SC) filter system using GaAs IGFET switches is described. The use of IGFET switches greatly eases the difficulties encountered in the realization of analog switch circuitry using MESFETs alone. The benefits accruing from this include reduced power consumption and circuit complexity. The system is fabricated on two separate dice mounted in a common package.<
