摘要：
Three switched-capacitor circuits are described which perform all filtering functions in a PCM voice CODEC. They use novel integrators and/or state-variable sections, which desensitize the overall response against stray-capacitance effects. 1 All filters are fully integrated on a CMOS test chip. The basic design considerations and the measured performance are discussed. Copyright © 1979 by The Institute of Electrical and Electronics Engineers, Inc.
