Abstract
A circuit for generating a temperature-stabilized reference voltage on a semiconductor chip includes a differential amplifier having a first input, a second input and an output. The circuit further includes a CTAT circuit configured to generate a CTAT voltage at an output thereof. A first resistor is coupled between the output of the differential amplifier and the output of the CTAT circuit. Further, the first resistor is connected between the first input and the second input of the differential amplifier.
