Abstract
A digital high frequency power detection circuit includes a peak detecting circuit and a peak computing circuit. The peak detecting circuit is operably coupled to detect a peak value of a high frequency signal and includes an amplifier, transistor, and capacitor. The amplifier has a 1input, 2input and an output, where the 1input is operably coupled to receive the high frequency signal. The transistor has an input, a first node, and a second node, where the input is coupled to the output of the amplifier, the second node is coupled to a supply voltage, and the first node is coupled to the 2input of the amplifier. The capacitor is operably coupled to the first node of the transistor and to a reference potential. The voltage imposed across the capacitor represents the peak value of the high frequency signal. The peak computing circuit is operably coupled to generate a digital peak value from the peak value.
