Abstract
A delta-sigma modulation analog to digital converter for converting an analog input signal to a digital output signal. The converter includes a clock generator for generating a very high frequency clock signal, a dither signal generator responsive to the clock signal generator for generating a dither signal which is synchronized with the clock signal, an adder coupled to the dither signal generator for combining the analog input signal and the dither signal, a delta-sigma modulation type quantizer coupled to the adder for quantizing the analog input signal and the dither signal in response to the clock signal and a data decimation circuit responsive to the clock signal and coupled to the delta-sigma modulation type quantizer for decimation prescribed quantization data from the quantized signal and producing a digital signal corresponding to the analog input signal.
