    摘要： An amplifier comprises a first amplifier circuit which amplifies a first signal to output an amplified first signal, a circuit which outputs a second signal corresponding to a difference between the first signal and the amplified first signal, a second amplifier circuit which amplifies the second signal to output an amplified second signal, a combine circuit which outputs an amplified signal by combining the amplified second signal with the amplified first signal, and a controller which controls a supply of a power to the first amplifier circuit and the second amplifier circuit and has a first mode to supply the power to the second amplifier circuit without supplying the power to the first amplifier circuit.

    摘要： A semiconductor integrated circuit device according to the present invention includes: 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.
