Abstract

A high frequency switched opamp modulator using switched-capacitor (SC) opamp-gain-error-compensation technique, was used to maximize speed and to maximize power comsumption. The resonator required for the bandpass modulator was implemented using modified double-sampling finite-gain-compensation (DSFGC). The resonator is a biquad consisting of two DSFGC integrators with capacitive input coupling to achieve large input signal swing at low voltage. For high speed operations, the opamps are decoupled for independent settling by realizing the resonator using delay non-inverting SC integrators and carrying out sign inversions for all SC feedback networks for stability.
