    Abstract: An integrated circuit (IC) die comprises a sensor, which includes a pulse generator and a pulse expander. The pulse generator comprises gate circuits coupled to each other in an in-series arrangement. An input of the pulse generator is coupled to receive a voltage and the pulse generator is to generate a first signal based on the voltage. The pulse generator is to generate a first pulse of the first signal based on an event wherein radiation from a laser is incident upon the pulse generator. The pulse expander is coupled to receive the first signal from the pulse generator and to generate a second signal based on the first signal, wherein a second pulse of the second signal is based on the first pulse. A first duration of the first pulse is less than a second duration of the second pulse.
