A method and circuit are disclosed for mirroring current. The circuit includes a reference branch through which a first current flows, and at least one mirror branch through which a second current flows that is proportional to the first current. The circuit further includes a current amplifier having an input coupled, via a capacitor, to the reference branch and an output coupled to one of the reference branch and the at least one mirror branch. The current amplifier provides, at relatively high frequencies, a current to the circuit that substantially compensates for current passing through a parasitic capacitance appearing in the circuit.
