ABSTRACT:
A system and method is provided to improve the performance of the sigma delta analog to digital converter (ADC). An input signal analog signal received though an input device is passed to a sigma delta modulator (SDM). The output of the modulator is passed through a low pass filter. An iterative algorithm and acceleration algorithm are applied to process the filter output signals to shape the noise components and to improve the performance of the sigma delta ADC. A distortion operator such as G operator, comprising of sigma delta modulator and multistage low pass filter (LPF) is used to suppress the shaped quantization noise.
