Abstract:
1. A semiconductor integrated circuit device, comprising: a sample circuit in which through current to be monitored flows during switching between transistors; a non-overlap circuit for outputting an output signal for the switching in the sample circuit; a current detector for detecting the through current flowing during the switching; and a current comparator in which a reference current value with respect to the through current has been set and which compares a current value detected by the current detector with the reference current value and outputs a result of the comparison to the non-overlap circuit. wherein the non-overlap circuit includes one of: wherein each of the delay circuit and the buffer includes a plurality of transistors connected in parallel and having different channel widths and different channel lengths, an ability of each of the delay circuit and the buffer is changed by selecting at least one of the transistors, and the delay time or the transition time of the output signal for the switching in the sample circuit is adjusted by the change of the ability.
