Abstract
An ESD protection circuit includes a pair of NPN lateral transistors electrically connected in series with the emitter of one of the transistors electrically connected to the collector of the other transistor. The bases of the two transistors are electrically connected together and are floating. The two transistors may be provided by two MOS transistors having N-type source and drains and P-type channel regions. The channels regions are connected together and are floating.
