Abstract
A negative voltage testing including a monitoring and triggering circuit coupled to a supply voltage rail of a device under test (DUT) and a switching circuit coupled to the monitoring and triggering circuit. The monitoring and triggering circuit is configured to cause the switching circuit to provide a first negative voltage to the supply voltage rail when a supply voltage on the supply voltage rail decays below a predetermined level during a first test of the DUT.
