摘要： In described examples, a voltage glitch detector includes a current source, a latch, and first, second, third, fourth, and fifth transistors. A source of the third transistor is coupled to a source of the second transistor, and a gate and drain of the third transistor is coupled to gates of the first and second transistors and a first terminal of the current source. A drain of the fourth transistor is coupled to a drain of the first transistor and an input of the latch. A source of the fifth transistor is coupled to a source of the fourth transistor and the second terminal of the current source. A gate and drain of the fifth transistor is coupled to a gate of the fourth transistor and a drain of the second transistor.
