Abstract
An electrostatic discharge (ESD) protection circuit is configured to protect a target circuit that operates in a cryogenic temperature is provided. The ESD protection circuit connects a terminal of the target circuit and a ground potential with no connection to a bias potential. When the ESD protection circuit receives a voltage potential at the terminal of the target circuit, the ESD protection circuit (i) disallows electrical current to flow through from the received voltage potential when the device is at a cryogenic temperature and (ii) allows electrical current to flow through from the received voltage potential when the device is at a room temperature.
