Abstract
A monolithic NMOS coder/decoder (codec) with associated CCD transversal minimum-phase filters has been successfully implemented. The codec operates by charge redistribution in a binaryweighted capacitor array, with a resistor chain to define individual steps. The experimental performance compares well with PCM codecs implemented with discrete components.
