Abstract
In some embodiments, a method of operating a sigma-delta analog-to-digital converter (ADC) includes converting an analog input signal into a sequence of digital data using a sigma-delta modulator of the sigma-delta ADC, setting a first configuration for a decimation filter of the sigma-delta ADC according to a first condition of a measurement window, filtering the sequence of digital data using a low-pass filter (LPF) of the decimation filter, and in response to a change in the measurement window, setting a second configuration for the decimation filter according to a second condition of the measurement window.
