Abstract

A current biasing circuit is provided, which is designed to suppress reference current drift caused by temperature variation with a low overall temperature coefficient of a constant-voltage circuit and at least one resistor. The constant-voltage circuit comprises a diode and/or a diode-connected transistor. This current biasing circuit is based on a current mirror architecture, is easy to implement, and is a relatively temperature-independent current source.
