Abstract
A current mirror circuit in accordance with the present invention overcomes many shortcomings of the prior art. A current mirror circuit for providing a current reference signal suitably includes at least one degeneration resistor to provide more degeneration for lower voltage noise while also including at least one clamping device to preventing saturation of the current mirror. The clamping device suitably comprises at least one diode, such as, for example, a Schottky-type diode. Moreover, the clamping device can be suitably configured to facilitate a higher slew rate of the current mirror circuit.
