ABSTRACT:
A cascoded current mirror device is disclosed that is capable of producing an output current that is a direct function of an input current received by that device. The cascoded current mirror includes at least two portions connected together in a cascode manner. Provision is also made for feedback connection between those portions. This feedback connection can, for example, be a buffering connection. Voltage signals are generated by this device that can be used to drive and control additional output stages. Each such additional output stage is capable of producing an additional output current.
