description 1. Technical Field A noise suppression circuit for suppressing above-ground noise is disclosed. The noise suppression circuit for suppressing noises includes a first inverter, a second inverter, and a one-shot circuit. The first inverter, connected to an input line, switches at a first voltage value above which a noise-coupling event is suspected. The second inverter, also connected to the input line, switches at a second voltage value above which a full-switch input is assumed. A first transistor is coupled to the input line. A second transistor passes an output of the second inverter to a gate of the first transistor when an output of the one-shot circuit is high. The third transistor holds the gate of the first transistor low when the output of the one-shot circuit is low.
