Electrostatic discharge protection solutions
Electrostatic discharge protection circuits and methods for protecting a core circuit from an electrostatic discharge event. The protection circuit may include a first anti-parallel diode pair including a first terminal coupled to an input/output pad, and a second anti-parallel diode pair including a second terminal coupled to a negative power supply voltage. The second anti-parallel diode pair is coupled in series with the first anti-parallel diode pair at a node. An offset pad is coupled to the node. The offset pad is configured to receive a first signal that is a duplicate of a second signal that is received at the input/output pad.
