A CMOS slope adaptive delta modulator

A slope adaptive A/D converter that reduces quantization noise through oversampling and feedback will be presented. A dynamic range of 90dB in the audio band, 15b resolution and total harmonic distortion of 0.17% at 1kHz has been achieved using a 3.5μm process.
