Current mirror for low supply voltage operation |
摘要 |
The present invention is an improved current mirror circuit. This improved current mirror circuit includes first and second transistors of the same conductivity type and have bases connected together. The first transistor is connected between a first supply terminal and an input terminal. The second transistor is connected between a first supply terminal and an output terminal. Included is a feedback circuit for providing a voltage feedback between the input terminal and the bases of the first and second transistors. Also included is a bias circuit for providing a bias current to the feedback circuit that is based on the input current.
