摘要：

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 binary-weighted capacitor array, with a resistor chain to define individual steps. The experimental performance compares well with PCM codecs implemented with discrete components. Copyright © 1979 by The Institute of Electrical and Electronics Engineers, Inc.
