Abstract
A radio frequency transmitter includes a digital-to-analog converter (DAC), a load circuit, and a modulator circuit. The load circuit is coupled to an output of the DAC. The modulator circuit is coupled to the DAC and the load circuit. The modulator circuit includes a driver circuit configured to provide a bias voltage to the load circuit, and an amplifier configured to receive an output of the DAC biased by an output of the load circuit.
