Abstract
A sigma-delta analog-to-digital converter (ADC) includes a feed-forward circuit, a finite-impulse-response (FIR) digital-to-analog converter (DAC), and a decimation filter. The feed-forward circuit is configured to receive an analog input signal and a feedback signal and generate a set of digital signals. Each feedback element of the FIR DAC includes a flip-flop and a reset circuit. The reset circuit is configured to receive a corresponding reset signal of a set of reset signals and output a reference output signal when the corresponding reset signal is deactivated. The reset signal of each feedback element is deactivated sequentially after each cycle of a clock signal that is received by the flip-flop associated with a corresponding reset circuit of each feedback element. The feedback signal is generated based on the reference output signal. The decimation filter is configured to generate a digital output signal based on the set of digital signals.
