ABSTRACT:
A sub-bandgap reference voltage generator, generates a pair of variable voltages one having a positive temperature coefficient and one having a negative voltage coefficient. The pair of voltages are added to generate an output voltage whose value and temperature may be varied. To achieve this, a first voltage having a positive temperature coefficient is multiplied by a first ratio defined by first and second resistive values to generate a second voltage. A third voltage having a negative temperature coefficient is multiplied by a second ratio defined by third and fourth resistive values to generate a fourth voltage. The second and fourth voltages are added together to generate the output voltage of the sub-bandgap voltage generator.
