Abstract
A laser detector includes a delay chain circuit and a warning circuit. The warning circuit is coupled to the delay chain circuit for generating a warning signal. The delay chain circuit includes N inverters coupled in series, an input terminal configured to receive an input voltage to the N inverters, and an output terminal configured to output an output voltage generated by the N inverters. N is a positive integer.
