Abstract
A method of controlling power in a circuit includes characterizing a power behavior of the circuit, from a circuit input to a circuit output during a manufacturing process of the circuit, wherein the characterizing may be at one or more of a wafer, chip or circuit board level, predicting the power behavior of the circuit on the basis of the characterizing, and controlling the power of signals transmitted from the output of the circuit on the basis of the predicting. An apparatus for controlling signal power in a circuit includes a transmitter to transmit an output signal, a receiver coupled to the transmitter by a loopback path, and a digital signal processor coupled to the transmitter and receiver, wherein the signal processor predicts and adjusts a power level of the output signal from the transmitter based on characterizing a loopback signal and known response characteristics of the circuit.
