Abstract
A method of adjusting a power amplifier may include producing a power measure of an output signal of the power amplifier and estimating an estimated transmission error of the output signal from the power measure. The estimated transmission error may be compared with a maximum error that is associated with a data rate of the output signal. A bias voltage that is input to the power amplifier may be decreased if the comparing determines that the estimated transmission error is less than the maximum error.
