Abstract
A reference generator includes a first, a second and an additional third current mirror for generating both a reference output current and a reference output voltage. As the reference output voltage only depends on the gate-source voltages of transistors which are fed with a constant current, the reference output voltage has a constant value and is substantially independent of the ambient temperature.
