Abstract
A receiver unit for a radio frequency (RF) tag is provided, including a first input terminal and a second input terminal each being connected to an antenna; a communication stage configured to demodulate and/or to modulate an incoming signal in the communication stage; and a power stage including a voltage converter circuit being configured to supply power to the receiver unit, and a regulation circuit being configured to limit an output voltage of the voltage converter circuit, wherein the regulation circuit includes a regulator circuit being configured to determine a first current value and a second current value, the second current value being a current value provided in addition to the first current value, and, if the second current value exceeds a predetermined threshold value, to supply a control signal to a limiter circuit configured to limit an input voltage of the voltage converter circuit.
