Abstract
A digital-to-analog converter circuit includes an input to receive a digital input signal having multiple bits. A modulation circuit is coupled to respond to less significant bits of the digital input signal by outputting a modulation signal that alternates between a logic low level and a logic high level. A digital-to-analog circuit is configured to convert more significant bits of the digital input signal to a first analog level. The digital-to-analog circuit is configured to alternate an analog output between the first analog level corresponding to a value of the more significant bits and a second analog level corresponding to one of adjacent values of the more significant bits in response to the modulation signal.
