Abstract
A supply voltage bias circuit includes: an output circuit which comprises a first transistor having a terminal from which output voltage or output current is supplied, the output voltage and output current having values proportional to a supply voltage at a supply line; a second transistor forming a current mirror circuit together with the first transistor, the second transistor being connected to a first connection node; a third transistor connected to the first connection node; and a current source connected between the first connection node and the supply line. Drains of the second and third transistors or sources of the second and third transistors are commonly connected to the first connection node. The drains or sources of the second and third transistors which are not connected to the first connection node are grounded or earthed. The first connection node is connected to a gate of the third transistor and is functioning as an output terminal of the bias circuit.
