Abstract: A transmitting and receiving circuit may include a first CMOS inverter configured to receive a first power supply signal and a first input signal. The transmitting and receiving circuit may include a first calculation amplifier including a non-inverted input terminal connected to an output terminal of the first CMOS inverter, and a first resistor connected between the output terminal of the first calculation amplifier and a first node. The output terminal of the first calculation amplifier and an inverted input terminal of the first calculation amplifier may be connected to each other. A first output signal may have a level smaller than that of the first input signal and may be output to the first node.
