Abstract
A current reference circuit includes a native metal oxide semiconductor field effect transistor (MOSFET). The native MOSFET includes a source terminal coupled to ground. The current reference circuit also includes a transistor and an amplifier circuit. The transistor includes a first terminal coupled to a drain terminal of the native MOSFET, a second terminal coupled to a power supply rail, and a third terminal coupled to the drain terminal of the native MOSFET. The amplifier circuit includes an input terminal coupled to the drain terminal of the native MOSFET, and an output terminal coupled to a gate terminal of the native MOSFET.
