ABSTRACT:
Method and device for protecting against electrostatic discharge. The method includes configuring a gate of at least one upper transistor of a transistor network connected between power rails to be biased to a prescribed value, and coupling an electrostatic discharge event to a gate of a lower transistor of the transistor network. The at least one upper and at least one lower transistors of the transistor network are respectively coupled between the power rails from a higher voltage to a lower voltage.
