Claim:
1. A low-voltage current mirror circuit comprising: at least a first power supply voltage source supplying a supply voltage to the current mirror circuit; an input stage electrically coupled to the power supply voltage source, the input stage comprising at least a current source and a first transistor; an output stage having an input node that is electrically coupled to an output node of the input stage, the output stage comprising a second transistor that operates as a first current mirror to the first transistor; a three-terminal voltage controlled current source (VCCS) having a first terminal, a second terminal and a third terminal, the first terminal of the VCCS being electrically coupled to the input stage, the second terminal of the VCCS being electrically coupled to ground; and a feedback loop electrically coupled on a first end to the third terminal of the VCCS and on a second end to the output and input nodes of the input and output stages, respectively, the feedback loop including a second current mirror that provides a compensation current to the output and input nodes of the input and output stages, respectively.
