Nth-Order Recursive Sigma-ADC Machinery at the Analogue: Digital Gateway

Authors: Hawksford, Malcolm J.

AES Convention 78 · Paper 2248 · May 1985

Abstract

A level compacting machine is proposed that combines a quantiser of limited resolution with oversampling and Nth-order feedback to maintain a more optimum signal transparency. The system, designated sigma-ADC (DDC), finds applications at the analogue-digital, digital-analogue gateways and allows amplifier studies to be applied directly to ADC. Other cited applications include oversampled DAC and code conversions to DSM and PWM formats. Both analogue-digital and all digital constructions are presented, together with supporting computer simulation using transient analysis procedures.
