Abstract
A circuit of an actively transmitting tag includes an antenna, a digitizer, a voltage-controlled oscillator (VCO), an output amplifier, a phase-displacement detector, and a regulator. The input of the digitizer connects to the antenna. The outputs of the digitizer and the output amplifier are connected to the input terminals of the phase-displacement detector. The output amplifier connects the output of the VCO to the antenna and the regulator connects the output of the phase-displacement detector to the VCO.
