More Information
Summary:A device includes a snapback clamp circuit configured to clamp a supply voltage in response to the supply voltage exceeding a trigger voltage level. In at least one embodiment, the snapback clamp circuit includes a clamp transistor and a programmable resistance portion that is responsive to a control signal to calibrate the trigger voltage level. Alternatively or in addition, the snapback clamp circuit may include a programmable bias device configured to calibrate the trigger voltage level by biasing a gate terminal of the clamp transistor. In another particular embodiment, a method of calibrating a snapback clamp circuit is disclosed. In another particular embodiment, a method of operating an integrated circuit is disclosed.
