    Abstract: A washing machine includes a housing; a drum disposed inside the housing and including a rotation shaft that extends in a vertical direction; and a filter unit disposed at an inner wall of the drum, configured to filter washing water flowing in a circumferential direction of the drum and to discharge the washing water in a radial direction inside of the drum. Accordingly, when a water current is formed inside the drum in the circumferential direction of the drum, the filter unit is disposed inside the drum so that foreign substances in the washing water rotated in the circumferential direction of the drum can be easily filtered.

    Abstract: Signal power management circuits and smart cards including the same are provided. For example, a signal power management circuit comprises a rectifier that is configured to rectify a received radio frequency signal and output a first rectified voltage, a first regulator that is configured to maintain the first rectified voltage at a predetermined first voltage level, and a second regulator that is configured to receive an output of the first regulator and maintain a second rectified voltage different from the first rectified voltage at a predetermined second voltage level. A signal detector of the signal power management circuit is configured to receive the first rectified voltage and the second rectified voltage and detect a signal component of the received radio frequency signal on the basis of a difference between the first voltage level of the first rectified voltage and the second voltage level of the second rectified voltage.

    Abstract: A near field communications (NFC) device includes a receiving module and a transmitting module. The receiving module includes a receiver receiving an analog signal that includes a carrier signal and data, an analog-to-digital converter converting the analog signal to a digital signal, and a filter filtering the digital signal. The transmitting module includes a direct current-direct current (DC-DC) converter having an operating frequency belonging to a stop band of the filter, and a transmitter receiving power from the DC-DC converter and receiving a system clock signal.
