Single junction bi-directional electrostatic discharge (ESD) protection circuit
In an embodiment, an ESD protection circuit may include a silicon-controlled rectifier (SCR) and a diode sharing a PN junction and forming a bi-directional ESD circuit. The single PN junction may reduce the capacitive load on the pin, which may allow the high speed circuit to meet its performance goals. In an embodiment, a floating P-well contact may be placed between two neighboring SCRs, to control triggering of the SCRs.
