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.

Abstract: An electronic device includes a housing, a wireless communication circuit, a wired communication interface, a processor, and a memory. The memory stores instructions that, when executed, cause the processor to connect with an external device by using the wireless communication circuit or the wired communication interface, to receive first information to set the electronic device as an access point (AP) from the external device, to receive second information on another AP from the external device, to configure the electronic device by using the first information, and to wirelessly broadcast a signal by using the wireless communication circuit, to allow wireless devices to connect to the AP.
