Claim:
1. A signal conversion circuit comprising: a half-wave generation circuit configured to receive an alternating current signal, and to generate a half-wave signal of a high potential side or a low potential side; and at least one inverter configured to receive the generated half-wave signal, and to generate a pulse signal, wherein the half-wave generation circuit includes a first MOS transistor and a second MOS transistor having a same conductivity type, a drain of the first MOS transistor and a gate of the second MOS transistor are connected to an alternating current signal input node to which the alternating current signal is input, a source and a backgate of the first MOS transistor and a source and a backgate of the second MOS transistor are commonly connected, and then connected to an input node of a first-stage inverter in the at least one inverter, and a gate of the first MOS transistor, and a drain of the second MOS transistor are grounded.
