Switched-capacitor second-order noise-shaping coder

The rapid development of digital processing in the fields of instrumentation, control and communications has generated a good deal of research into simple, easily integrable, high-resolution A/D converters. Given the significant promise such converters offer for future application, a switched-capacitor version of a second-order noise-shaping coder intended for high-resolution conversion has been realised. This coder has been used successfully to produce a PCM signal.
