Abstract
Provided herein are segmented digital to analog converters (DACs), methods for use therewith, and systems that include one or more such DACs. According to an embodiment, a DAC includes a plurality of sub-DACs, a DAC input adapted to receive a multi-bit digital input and a DAC output adapted to output an analog output current in response to and indicative of the digital input. Each sub-DAC is adapted to receive a separate reference current that specifies a transfer function of the sub-DAC. A magnitude of the reference current provided to each sub-DAC is separately programmable to thereby separately control a gain of each sub-DAC.
