DIGITAL-TO-ANALOG CONVERTER

摘要

A digital-to-analog converter (DAC) circuit includes a first DAC that produces a first analog output signal based upon a received multi-bit digital data and upon a received clock. A second DAC that produces a second analog output signal based upon the received multi-bit digital data and upon the received clock, wherein the first and second DACs are connected in parallel and process the same input signal comprising the multi-bit digital data. In one embodiment, the DACs produce differential signals. A low pass filter connected to receive the first and second analog outputs is configured to sum the first and second analog outputs and to filter the summed first and second analog outputs to produce an ingoing analog signal. An amplifier connected to receive the ingoing analog signal to produce an amplified ingoing analog signal.
