Abstract: A power level determination device provides an output voltage usable as a specific reference power level corresponding to each RF input power level. The device includes a peak detector, which detects a pulse-type signal at its input and provides a non-pulse-type signal at its output. N comparators are provided, where N is an integer. Each of the N comparators has an output, a first input coupled to the output of the peak detector, and a second input coupled to a respectively different threshold voltage. The first one of the N comparators has a maximum threshold voltage. The threshold voltages decrease monotonically from No. 1 to No. N. N exclusive-OR components are provided. A first one of the N exclusive-OR components is coupled to ground and to the output of a first one of the N comparators.
