Abstract
A voltage reference circuit comprising: a main amplifier, having an output-terminal for providing a reference-voltage-output-signal, wherein the output-terminal is connected to the first-input-terminal; an offset-stage, connected to at least one of a first-input-terminal and a second-input-terminal of the main amplifier; and a PN junction. The PN junction is configured, in use, to provide a junction-voltage, between the first-junction-terminal and the second-junction-terminal, wherein the junction-voltage decreases with increasing temperature. The offset-stage is configured, in use, to provide an offset-voltage between the first-input-terminal and the second-input-terminal, wherein the offset-voltage increases with increasing temperature.
