An integrated circuit has a current sense amplifier that includes a voltage comparator having a first input, a second input and an output; a first clamping device coupled between the first input of the voltage comparator and a first input signal node, a second clamping device coupled between the second input of the voltage comparator and a second input signal node, a current mirror having a first side and a second side, the current mirror first side including a first transistor coupled between a voltage source and the first clamping device and the current mirror second side including a second transistor coupled between the voltage source and the second clamping device, and a sensing scheme including an actively balanced capacitance coupled to the source and drain of the second transistor.
