Abstract
A current sense amplifier includes: first and second intermediate nodes coupled to first and second nodes of a sense resistor by a chopper, and to respective branches of a current mirror; a differential amplifier having inputs coupled to the first and second intermediate nodes and adapted to generate first and second voltage signals; and first and second transistors adapted to be controlled by the first and second voltage signals respectively and each having one of its main current conducting nodes coupled to a respective one of the first and second intermediate nodes.
