Abstract
A sigma-delta analog-to-digital converter comprises a sigma-delta modulator; and an ADC filter that receives a segment of L binary samples from the sigma-delta modulator, L being a positive integer. The ADC filter includes a predictor circuit that determines whether a power consumption of a first summing method would be higher than a power consumption of a second summing method, based on a content of the segment, and an accumulator circuit that calculates an output using the first summing method in a case where the power consumption of the first summing method would be lower than the power consumption of the second summing method, and using the second summing method in a case where the power consumption of the first summing method would be higher than the power consumption of the second summing method.
