Abstract
An integrated circuit (IC) is provided with a plurality of diode based mm-wave peak voltage detectors (PVD)s. During a testing phase, a multi-point low frequency calibration test is performed on one or more of the PVDs to determine and store a set of alternating current (AC) coefficients. During operation of the IC, a current-voltage sweep is performed on a selected one of the PVDs to determine a process and temperature direct current (DC) coefficient. A peak voltage produced by the PVD in response to a high frequency radio frequency (RF) signal is measured to produce a first measured voltage. An approximate power of the RF signal is calculated by adjusting the first measured voltage using the DC coefficient and the AC coefficient.
