ABSTRACT:
An electronic system comprises an automatic power control (APC) unit, an adjustment unit, and a calibration unit. The automatic power control (APC) unit receives a first input signal and a second input signal and generates an output signal. An adjustment unit coupled to the first input terminal of the APC unit generates a voltage offset according to an adjustment signal. The calibration unit provides the adjustment signal with a series of values. The calibration unit monitors the output signal until the output signal changes states.
