Abstract
A ground bounce generator includes a resistor and at least one switch coupled in parallel with the resistor. The ground bounce generator is in a device under test circuit including a source, at least one ground bounce generator, at least one device under test, and a ground. The device under test is coupled in series between the source and the ground bounce generator. The device under test and the ground bounce generator are coupled in series between the source and the ground.
Claims19
A device under test circuit, comprising:
- a source;
- at least one ground bounce generator, wherein each ground bounce generator comprises:
- a resistor;
