HEAT STABLE REFERENCE VOLTAGE SOURCE BASE ON STABILITRON Russian patent published in 2014 - IPC G05F3/16 G06F3/02 

FIELD: electricity.

SUBSTANCE: reference voltage source comprises the current source coupled between the supply bus and base of the first transistor, which collector is coupled to the supply bus and emitter to the device output, a stabilitron coupled by its cathode to the base of the first transistor, the second and third transistors, at that emitters of the second and third transistors are coupled to the common bus, base of the second transistor is joint with the collector of the second transistor and base of the third one and coupled to anode of the stabilitron, while collector of the third transistor is coupled to the device output.

EFFECT: increasing temperature stability of output voltage.
