This paper proposes high resolution oversampling analog-to- digital and digital-to-analog converters. These converters utilize multistage noise shaping modulation techniques which can be implemented with VLSI MOS technology. The modulators consist of multiconnected single integration delta-sigma modulation loops. Quantization noise in the first delta-sigma loop is requantized by the next delta-sigma loop and cancelled by adding the requantized noise to the first stage signal. Quantization noise in the modulated signal is suppressed by double or multiple integration gain. Modulator resolution increases with the number of stages without feedback loop instability problems. A three-stage multistage noise shaping modulator with 1-bit quantization achieves the equivalent of 16-bit resolution for Hi-Fi audio band at 2 MHz sampling rate. Simulation results show that analog-to- digital and digital-to-analog converter circuits, constructed of switched capacitors, can be used without highly accurate components.
