A current sense circuit is described herein. In accordance with one embodiment, the circuit comprises: a first circuit node and a second circuit node configured to be coupled to a first terminal and a second terminal of a current sense resistor, respectively; an differential amplifier having a first input and a second input which are coupled to the first circuit node and the second circuit node via a first input resistor and a second input resistor; a voltage source, configured to set the voltage at the first input of the differential amplifier to a predefined DC voltage; and a controllable current mirror configured to sink or source a first current in its input branch based on one or more outputs of the differential amplifier and to generate a corresponding second current in its output branch. The input branch is coupled to the second input of the differential amplifier. A biasing circuit is configured to generate a bias current and is coupled to the controllable current mirror to superpose the bias current with either the first current or the second current.
