Abstract :
A second generation LSI codec has been implemented. In this chip, switched-capacitor filters, a charge redistribution encoder and decoder, voltage references, a signaling logic circuit, and all necessary functions for voice-PCM conversion are integrated. The authors describe the codec and summarizes its characteristics.
