ABSTRACT:
A reference voltage generating circuit for converting a first source voltage to a second source voltage includes a positive thermal compensation circuit connected between the first source voltage and ground voltage and having a positive thermal coefficient for positively compensating the second source voltage with respect to temperature variations, and a negative thermal compensation circuit responsive to the output of the positive thermal compensation circuit and having a negative thermal coefficient for negatively compensating the second source voltage with respect to temperature variations, wherein the positive and negative thermal coefficients counter-balance each other so as to stabilize the second source voltage.
