ABSTRACT:
A sigma-delta modulator includes an adder, a filter, a quantizer, and a clock rate controller. The adder receives an input signal and an output signal to generate a summation signal. The filter is coupled to the adder and filters the summation signal to generate a filtered signal. The quantizer is coupled to the filter as well as the adder and quantizes the filtered signal to generate the output signal according to a first clock signal. The clock rate controller is coupled to the quantizer and generates the first clock signal, wherein a frequency of the first clock signal is variable.
