ABSTRACT:
An improved logic interface circuit having both a low current drain under rest conditions and a great stability in respect of temperature variations, is based on an original and effective implementation of the so-called bandgap-type voltage reference circuit, according to which the intrinsic gain of the bandgap system is not utilized, as normally happens in such voltage reference circuits for providing a negative feedback capable of compensating the temperature coefficient of the V.sub.be, but for obtaining, under open loop conditions, a transition of the output of the circuit when the input of the circuit crosses a certain threshold voltage.
