Abstract
A temperature corrected voltage bandgap circuit is provided. The circuit includes first and second diode connected transistors. A first switched compare circuit is coupled to the one transistor to inject or remove a first current into or from the transistor. The first current is selected to correct for curvature in the output voltage of the bandgap circuit at one of hotter or colder temperatures.
