Abstract
A floating current mirror circuit is disclosed which achieves high open loop gain without additional voltage gain stages leading to frequency compensation and increased power dissipation. The output of the circuit has only a first pole and is designed to be coupled to a second current source, a base coupled to the first terminal of the diode, and an emitter coupled to the floating node. A second bipolar transistor has a base coupled to the collector of the first transistor, and emitter coupled to the floating node.
