Abstract:
A sigma-delta analog to digital converter (ADC) includes an M-bit digital-to-analog converter (DAC); a loop filter coupled to receive an output from DAC; and a variable level quantizer configured to provide a uniform quantization function by switching between an N-level quantizer function and an N−1 level quantizer function.
