Bandpass delta-sigma modulator
A bandpass delta-sigma modulator is formed to include a bandpass filtering circuit that bandpass filters an input signal. An analog-to-digital converter (ADC) receives output of the bandpass filtering circuit and generates an output quantization code. A digital filter receives the output quantization code. A digital-to-analog converter (DAC) receives output of the digital filter and scales the value of the output quantization code by DAC coefficients to the bandpass filtering circuit.
