Abstract
A continuous time ΔΣ analog-to-digital converter with mitigation bit shifting multiplex array including a loop filter, a VCO responsive to analog signal configured to adjust the output frequency based on the magnitude of the analog signal and produce a digital output, a multi-stage phase quantizer responsive to the digital output configured to determine the phase of the VCO by comparing the phase of the VCO for a particular sample to a reference phase at said particular sample and generate a quantized phase difference value, and a multiplexer array coupled to the multi-stage phase quantizer configured to shift selected misaligned bits of the quantized phase difference value by a predetermined amount of bits to mitigate bit shifting of the multi-stage phase quantizer.
