Abstract
A system comprising a current sensor for sensing an average output current and/or an average input current of a circuit is presented. There is a first switch, the first switch being arranged to selectively couple a sensing node of the circuit to a first voltage, wherein the current sensor comprises a pulse density modulator configured to generate a pulse density modulated signal. The pulse density modulated signal is dependent on an average current flowing through the first switch. The current sensor is configured to sense the average output current and/or the average input current of the circuit using the pulse density modulated signal.
