  • Abstract
    A switched-capacitor integrator pair capable of forming a two integrator loop using a biphase clocking scheme and having low sensitivity to nonideal op-amp (OA) effects is presented. The OAs have continuous-time feedback paths, so avoiding voltage spikes caused by slewing. Expressions for response error and the results of a ladder filter simulation are given.<>
