Abstract
A method for providing a voltage reference at a present operating temperature in a circuit is provided. The circuit comprises a first MOS transistor having a first threshold voltage; and a second MOS transistor having a second threshold voltage different from the first threshold voltage is provided. Temperature insensitivity is obtained by compensating the difference between the first threshold voltage and the second threshold voltage with a parameter representative of the present operating temperature.
