IPC: H03M3/00
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.

Abstract: Representative implementations of devices and techniques provide analog to digital conversion of an analog input. A multistage modulator using a feed-forward technique can alternately convert integrated samples of the analog input to digital representations. For example, the modulator is arranged to alternately output the digital representations to form a digital representation of the analog input.
