Delta sigma modulator

Abstract:

A delta-sigma modulator includes a first amplifier having an input, a feedback control input, and an output. The input is a first input of the delta-sigma modulator. The delta-sigma modulator further includes a first integrator and a first quantizer. The first integrator has an input and an output. The output of the first amplifier is coupled to the input of the first integrator. The first quantizer has an input and an output. The output of the first quantizer is coupled to the feedback control input of the first amplifier.
