ABSTRACT:
An apparatus and a method to reduce temperature dependence of a reference voltage have been presented. In one embodiment, the method includes generating a reference voltage associated with a difference between a first threshold voltage of a first transistor and a second threshold voltage of a second transistor. The method may further include biasing the first transistor and the second transistor at a predetermined ratio of currents of the first and the second transistors to reduce temperature dependence of the reference voltage.
