Claim 11:
12. An integrated circuit (IC), comprising:
a transmitter configured to generate a transmission signal;
a PLL comprising a voltage-controlled oscillator (VCO) configured to generate an output signal having an amplitude based on a control voltage, the PLL configured to control a frequency of the transmission signal;
a peak detector comprising:
a plurality of amplitude detection circuits coupled in parallel to a first signal input and a second signal input, each of the plurality of amplitude detection circuits configured to generate a voltage on an output indicating a voltage difference between the first signal input and the second signal input; and
an averaging circuit coupled to the output of each of the plurality of amplitude detection circuits, the averaging circuit configured to generate, on a peak detector output, an average voltage comprising an average of the voltages generated on the outputs of the plurality of amplitude detection circuits; and

a range sensor configured to:
determine whether the average voltage on the peak detector output is outside a voltage range; and
adjust the control voltage in response to determining the average voltage on the peak detector output is outside a voltage range.
