Radio frequency current steering digital to analog converter

A digital-to-analog converter (DAC), comprising:

• a decoder operable to output a data signal in response to binary input codes;
• a plurality of output cells coupled between the decoder and a load circuit to provide an analog output signal centered at a carrier frequency, each of the plurality of output cells comprising:
• a switch circuit coupled to the load circuit;
• a driver having an input and an output, the output operable to control the switch;
• and
• combinatorial logic having a data input operable to receive a respective bit of the data signal, a clock input operable to receive a clock signal, and an output, coupled to the input of the driver, the combinatorial logic operable to exclusively OR the data input and the clock input.

A method of digital-to-analog conversion, comprising:

• generating a data signal in response to binary input codes;
• operating a plurality of output cells to provide an analog output signal centered at a carrier frequency, where each of the plurality of output cells is operated by:
• exclusively ORing a respective bit of the data signal and a clock signal to generate a control signal;
• and
• selectively driving a load circuit based on the control signal.
