Abstract
Devices and methods are provided for monitoring a transient time in a device under test. A circuit includes a transient edge clipper circuit electrically coupled to the device under test. The transient edge clipper circuit is configured to remove voltage levels of a voltage waveform of the device under test which exceed a threshold range to generate a clipped voltage waveform. The circuit also includes logic circuitry electrically coupled to the transient edge clipper circuit. The logic circuitry is configured to generate a time delayed pulse signal representation of the clipped voltage waveform by injecting a predetermined time delay. The circuit also includes a converter circuit electrically coupled to the logic circuitry. The converter circuit is configured to generate a current signal based on the pulse signal representations.
