ABSTRACT:
A buffer circuit comprises an interface node, a bipolar transistor having a collector connected to a first power source, an emitter connected to a second power source, and a base, for transferring a signal supplied to and from the interface node, and a diode structure formed between the emitter and base of the bipolar transistor, the diode structure containing a PN junction reversely coupled across the emitter-base junction of the bipolar transistor.
