Abstract
An automatic power tuning system and method, and a transmitter employing either the system or the method. In one embodiment, the system includes: (1) a power detector circuit coupled to an output of a transmitter, the transmitter having an integrator with a first, reference integrator current power control input, a second, integrator capacitor power control input and a plurality of driver fingers selectably employable by a third, driver finger power control input, the power detector configured to generate signals indicating an output voltage of the transmitter and (2) a digital processing circuit coupled to the power detector circuit and configured to employ the signals to determine at least near-optimum reference integrator current and integrator capacitor settings and select a number of driver fingers to employ to drive the output voltage.
