ABSTRACT:
A constant power voltage circuit includes a first transistor for generating a collector current, a second transistor for generating a collector current, a third transistor, the collector of which is connected to the collector of the first transistor, a fourth transistor, the collector of which is connected to the collector of the second transistor, an emitter-grounded amplifier circuit including a fifth transistor for providing a feedback loop, with a fifth transistor, the collector which is connected to a constant current circuit and the base current of the third and the fourth transistors, being outputted from the constant current circuit upon the application of a power source.
