Abstract
A reference circuit constituted of: a voltage/current bias circuitry; a first transistor coupled between a common voltage and an first bias circuitry output; a second transistor coupled between the common voltage and a second bias circuitry output; a third transistor coupled between the common voltage and an output providing a temperature and supply invariant current; a resistor coupled between the second transistor and the second output of the bias circuitry; and an output providing a temperature and supply invariant voltage coupled between the resistor and the second transistor, the voltage output terminal further coupled to a gate of the third transistor, wherein the bias circuitry is arranged, in cooperation with the first transistor, to generate a first current at the first output thereof, and, in cooperation with the second transistor, to generate a second current at the second output thereof, the current magnitudes exhibiting a ratio of a predetermined value.
