Abstract
The present disclosure relates to an integrated circuit. The integrated circuit comprises a silicon on insulator (SOI) device separated from a SOI substrate by an insulation layer. The SOI device comprises a power supply terminal, a ground terminal, a first I/O terminal and a second I/O terminal. An electrostatic discharge (ESD) protection circuit is integrated with the SOI device. The ESD protection circuit is configured to shunt current between two terminals of the SOI device during an ESD surge event. An electrostatic discharge (ESD) enhancement circuit is integrated with the SOI device. The ESD enhancement circuit is configured to clamping the SOI substrate to a lower potential of the two terminals of the SOI device.
