Abstract
An electrostatic discharge (ESD) protection circuit for protecting a protected circuit is coupled to an input pad. The ESD circuit includes a nanotube switch electrically having a control. The switch is coupled to the protected circuit and to a discharge path. The nanotube switch is controllable, in response to electrical stimulation of the control, between a de-activated state and an activated state. The activated state creates a current path so that a signal on the input pad flows to the discharge path to cause the signal at the input pad to remain within a predefined operable range for the protected circuit. The nanotube switch, the input pad, and the protected circuit may be on a semiconductor chip. The nanotube switch may be on a chip carrier. The deactivated and activated states may be volatile or non-volatile depending on the embodiment.
