摘要： In some examples, a circuit arrangement has a first output node for connection to a first electrode of the electrochemical cell, a second output node for connection to a second electrode of the electrochemical cell and a third output node for connection to a third electrode of the electrochemical cell. The circuit arrangement further has an interface circuit designed to output a first voltage at the first output node and further designed to output a third voltage at the third output node, which third voltage is set such that a second voltage at the second output node corresponds to a reference voltage. A control unit is designed to set the first voltage such that a predetermined cell voltage is applied between the first and the second output node. The control circuit is further designed to adjust the reference voltage depending on the electrical state of the electrochemical cell.

摘要： A power supply circuit is described herein which is capable of sourcing energy from an NFC antenna. In one embodiment, the circuit comprises a rectifier circuit configured to be coupled to an NFC antenna for receiving an antenna voltage, a filter coupled to an output of the rectifier circuit and configured to provide the rectified and smoothed antenna voltage as supply voltage, and a current limiting device coupled between the filter and an output node and configured to limit an output current provided at the output node dependent on a control signal. Further, the power supply circuit comprises a control circuit configured to receive the supply voltage and a reference voltage and to generate the control signal dependent on a difference between the reference voltage and the supply voltage.
