A modulator integrator circuit includes an amplifier having a capacitive feedback connection, a variable voltage generator, a fixed voltage reference, and a capacitor having a first plate and a second plate. The first plate of the capacitor is coupled to the variable voltage generator. The modulator reference circuit further includes a first switch that selectively couples the second plate of the capacitor to the amplifier and a second switch that selectively couples the second plate of the capacitor to the fixed voltage reference.
