Abstract:
A representative electrostatic discharge (ESD) protection circuit includes a silicon-controlled rectifier (SCR) that is electrically coupled to the output of a power amplifier; an ESD detection circuit that triggers the SCR responsive to detect an electrostatic discharge on an ESD bus; and an ESD clamp circuit that is coupled to the first voltage line.
