TRANSMISSION DEVICE, RECEPTION DEVICE, TRANSMISSION/RECEPTION DEVICE, AND TRANSMISSION/RECEPTION METHOD

摘要

Disclosed is a transmission/reception device which outputs direct current voltage via noncontact communication, wherein the area and the amount of power consumption of a reception device is reduced. The reception device is equipped with: a reception coil in which an electromotive force is induced when a first current for which the rise time is shorter than the fall time, and a second current the direction of which is opposite that of the first current and for which the rise time is longer than the fall time, flow in a transmission coil; a filter circuit that filters the electromotive force that has been induced in the reception coil; and an integration circuit that integrates the current output by the filter circuit.
