  • Abstract
    This paper describes a 16-bit stereo audio ΣΔA/D converter. It consists of two identical novel stability fifth-order switched capacitor ΣΔ modulators using dynamic dither scheme, bandgap circuits and a decimation digital filter. A new multistage comb filter was used for the front end decimation filter. The ADC was implemented in 0.5-μm 5-V CMOS technology. The chip die area occupies only 4.1 *2.4mm2and dissipates 90mW.
