A dual delta-sigma modulator includes a first modulator, a second modulator, and a shared amplifier coupled to the first and second modulators. The first modulator includes an integrator configured to generate a first modulator output signal. The second modulator includes a second integrator configured to generate a second modulator output signal. The shared amplifier is configured to assist the first integrator integrating a difference between a first analog input signal and a first modulator output signal from the first modulator during a first period of time and to assist the second integrator integrate a difference between a second analog input signal and a second modulator output signal from the second modulator during a second period of time.
