Abstract
An integrated circuit system includes a first device in a first power domain, and a second device coupled to the first device in a second power domain. A circuit module is coupled between the first device and a power supply voltage or between the first device and a complementary power supply voltage in the first power domain for increasing an impedance against an ESD current flowing from the first device to the second device during an ESD event.
