Abstract

This paper presents a ΣΔ modulator (ΣΔM) which combines single-bit and multi-bit quantization in a cascade architecture to obtain high resolution with low oversampling ratio. It is less sensitive to the non-linearity of the DAC than those previously reported, thus enabling the use of very simple analog circuitry with neither calibration nor trimming required.
