Abstract
A current mirror circuit included in a computer system that includes a mirror stage circuit and a feedback circuit is disclosed. The mirror stage circuit generates a mirror current in an output node using a reference current. The feedback circuit adjusts the value of the mirror current based on a voltage level of the output node to increase the output impedance of the current mirror circuit.
