Abstract :
A digital A/D converter (DAD) for audio applications is presented. The whole converter consists only of digital CMOS logic and some resistors and capacitors. No linear amplifier is needed. This kind of A/D converter is mostly a pure digital design. A prototype for 20 kHz audio applications with a 80 dB dynamic range and 44.1 kHz output sample rate was designed and processed in 0.18 /spl mu/m CMOS.
