  • Laser detecting circuit and semiconductor apparatus including the same
    Patent number: 12230588
    Abstract: A laser detecting circuit is provided. The laser detecting circuit includes a latch circuit with a first inverter configured to invert a first output signal at a first node to generate a second output signal at a second node, and a second inverter configured to generate the first output signal based on the second output signal. The second inverter includes a plurality of PMOS transistors connected in series between a first source voltage and the first node, and a plurality of NMOS transistors. A gate of each of the plurality of PMOS transistors is connected to the second node, and a drain of each of the plurality of NMOS transistors is connected to the first node. The plurality of NMOS transistors includes dummy NMOS transistors and normal NMOS transistors.
