Electrostatic discharge protected circuits
Abstract:
A method for designing an ESD protected analog circuit is described. The method includes creating an analog circuit design comprising a plurality of interconnected functional components and circuit-level ESD protection components with predetermined electric properties for achieving a predetermined analog performance during normal operation of the circuit as well as a predetermined ESD robustness during an ESD event on the circuit. At least one ESD event is simulated on the analog circuit design to identify at least one weak spot in the circuit. Component-level ESD protection components are added into the analog circuit design around each identified weak spot to reduce failure of the weak spot during an ESD event.
