Abstract: Vanadium oxide exhibits a substantial and relatively abrupt change in conductivity as the temperature of the material is varied through a particular characteristic temperature (about 68* C.). In accordance with our invention, a vanadium oxide resistor is employed as a temperature-sensing element in the control circuit of a heater to stabilize the operating temperature of an electronic circuit at about 68* C. over a wide range of ambient temperatures.
