Abstract
An ESD protection circuit includes an input port, a resistor, a BJT, and a diode. The BJT has an emitter, a base, and a collector. The emitter of the BJT is coupled to the input port. The base of the BJT is coupled through the resistor to the input port. The diode has a first terminal and a second terminal. The first terminal of the diode is the collector of the BJT. The second terminal of the diode is coupled to a supply voltage.
