Abstract
A modulator is configured to respond to input swings by providing a feedback voltage via a feedback path to compromise an increase in noise and distortion power with increasing signal power at signal levels exceeding a predetermined threshold. A digital-to-analog converter (DAC) generates a feedback voltage with a resistor string biased with a given current and switches as a function of an input value to mitigate the voltage swing at a summing node.
