Abstract
A circuit for generating a temperature-stabilized reference voltage uses the current-mode technique, in which two partial currents are superimposed on each other and converted into the reference voltage. One partial current is generated by an asymmetric differential amplifier with two lateral bipolar transistors of different area. In order to generate the other partial current, an electrical resistor is disposed between the common node of the differential amplifier and ground.
