Abstract
An electronic current mirror circuit particularly suitable for use in radio frequency (RF) and microwave power amplifiers. The electronic circuit includes a first current mirror circuit and a second current mirror circuit. The first current mirror circuit includes a first input circuit path and a first output circuit path, the first input circuit path is operated at a first supply voltage and the first output circuit path is operated at a second supply voltage. The second current mirror circuit includes a second input circuit path and a second output circuit path, the second input circuit path is operated at the second supply voltage, and the second output circuit path is connected to the first input circuit path so that variations in a current through the first output circuit path are compensated by a current in the second output circuit path.
