Abstract
Analog modulator circuitry,includes an integrator,. First switched capacitor circuitry,selectively samples a first amount of charge from a feedback signal and couples that first amount of charge to the first and second inputs of the integrator. Second switched capacitor circuitry,selectively samples a second amount of charge from the feedback signal and couples that second amount of charge to the first and second inputs of the integrator stage to selectively compensate for an offset of an input signal to the integrator with respect to a reference voltage.
