Abstract
A circuit for generating a bandgap voltage includes a circuit module for generation of a base-emitter voltage difference formed by a pair of PNP bipolar substrate transistors which identify a first current path and a second current path. A first current mirror of an n type is connected between the first and second branches and is further connected via a resistance for adjustment of the bandgap voltage to the second bipolar transistor. A second current mirror of a p type is connected between the first and second branches, and connected so that the current mirrors repeat current of each other. In operation to generate the bandgap voltage, current flows from the supply voltage to ground only through said the first and second bipolar substrate transistors.
