Abstract
A method of detecting a power level of an RF signal includes driving an internal node of a power detection circuit to a DC node voltage level, generating, based on the DC node voltage level, a first component of an output voltage on an output node of the power detection circuit, receiving the RF signal on an input node of the power detection circuit, dividing the RF signal to generate a modulation signal on the internal node, and generating, by at least partially rectifying the modulation signal, a second component of the output voltage on the power detection circuit output node.
