Abstract
A digital decimation filtering circuit of an analog to digital conversion circuit includes an n-tap anti-aliasing filter operable to receive a 1-bit analog to digital converter (ADC) output signal at an oversampling rate and filter the 1-bit ADC output signal to remove frequencies higher than a selected cut-off frequency to produce an n-bit filtered signal at a first data output rate. The digital decimation filtering circuit further includes a decimator operable to receive the n-bit filtered signal at the first data output rate, decimate the n-bit filtered signal by a decimation factor to produce a set of output signals, and sum the set of outputs to produce a decimated signal at a second data output rate. The first data output rate is greater than the second data output rate.
