Abstract

The invention concerns a voltage source. The principle for the invention is to use a constant power source I1 integrated in the circuit and connected to the operating voltage supply Vcc in the integrated circuit IC in order to create a reference voltage Vref. The integrated circuit is preferably an operation amplifier which constitutes a difference amplifier which detects the voltage difference between the output voltage of the power source and the reference voltage. <IMAGE>
