Abstract
A delta sigma modulator circuit comprises a forward circuit path including a first integrator stage and an analog-to-digital converter (ADC) circuit, wherein a transfer function of the forward circuit path includes a signal gain element of m, wherein m is a positive integer; an input path to the first integrator stage, wherein a transfer function of the input path includes a signal gain element of l/m; and a feedback circuit path operatively coupled to an output of the ADC circuit and an inverting input of an op amp of the first integrator stage, wherein the feedback circuit path includes at least a first digital-to-analog converter (DAC) circuit and a transfer function of the feedback circuit path includes a signal gain element of l/m.
