Abstract: A circuit for compensating for the effects of light exposure is provided. The circuit includes a first circuit and a light compensation circuit. The first circuit has an output terminal for providing a first current, wherein at least a portion of the first current is a function of a first light sensitive circuit component. The compensation circuit has a current mirror and a second light sensitive circuit component. The current mirror has an input terminal coupled to receive a second current that is mirrored from the first current, and an output terminal coupled to provide a third current responsive to the second current. The second light sensitive circuit component is configured to be similar to the first light sensitive circuit component and to compensate for a light induced current provided by the first light sensitive circuit component so that the third current is provided without a light induced current component.

Abstract: It is described a leakage compensation circuit for a measurement device which comprises a measurement circuit with a leaking device that is connected to a measurement path and causes a leakage current. The leakage compensation circuit comprises: i) a replica device of the leaking device, wherein the replica device is connected to a replica path, and wherein the replica device is configured to cause a replica leakage current that is essentially equal to the leakage current of the leaking device, ii) a voltage regulator which is connected to the measurement path and to the replica path, wherein the voltage regulator is configured to regulate the voltage in the replica path based on the voltage of the measurement path, and iii) a current mirror which is connected to the measurement path and to the replica path, wherein the current mirror is configured to mirror the replica leakage current of the replica device into the measurement path.

Abstract: A radio frequency (RF) voltage limiter for a radio frequency identification (RFID) transponder is provided. The RF voltage limiter includes an envelope detector configured to track an envelope of a signal received at the antenna. The envelope detector has an output for providing an envelope signal. A peak detector is included and has an input coupled to the output of the envelope detector. The peak detector includes a current mirror having an input coupled to the output of the envelope detector, and an output configured to provide a control signal. A shunt circuit is coupled to provide an impedance to the antenna in response to the control signal. The impedance decreases with an increasing voltage of the control signal to limit a maximum voltage at the antenna. In another embodiment, a method is provided for limiting a RF voltage at the antenna.
