Abstract :
A high-frequency gain-compensated switched-capacitor (SC) integrator is presented which is based on a four-input differential-output operational amplifier. The circuit uses an accurate prediction which also accounts for the current input sample and provides an intrinsically fast operation. Gain and phase error smaller than previous designs is achieved
