Abstract
A voltage reference source includes a source block, a first resistor having a first terminal coupled to a first terminal of the source block, a reference output for providing a reference voltage, and a first and a second mirror transistor forming a first current mirror. The first mirror transistor couples a second terminal of the source block to a supply voltage terminal and the second mirror transistor couples the reference output to the supply voltage terminal. A series connection of a second resistor and a diode is arranged between the reference output and the first terminal of the first resistor. A mirror current flows through the second mirror transistor and the series connection to the first terminal of the first resistor.
