US 2018/0006734 A1 · RECEPTION DEVICE AND TRANSMISSION/RECEPTION SYSTEM INCLUDING THE SAME

Abstract

The reception device includes a base member, a first electrode, a second electrode, a differential amplifier, and a circuit board. The base member includes a first surface and a second surface. The first electrode is provided on the first surface and configured to receive a reception signal. The second electrode is provided on the second surface and configured to receive a reference voltage. The differential amplifier is configured to amplify a potential difference between the reception signal and the reference voltage. The circuit board is configured to provide a power voltage and a reference ground to the differential amplifier. A distance between the circuit board and the first electrode is smaller than a distance between the circuit board and the second electrode. According to an embodiment of the inventive concept, the amplification performance of the reception device using a human body as a medium is improved.
