Charger for mobile devices for use in automobile

There is provided a charging apparatus and a wireless charging apparatus that facilitate display of a fully charged state using a monochromatic display device. The charging apparatus and the wireless charging apparatus include a power supply unit supplying a charging power, a charging unit supplying the charging power to an external charging target device, a charging control unit controlling a charging state of the charging unit, a display unit that displays the charging state under the control of the charging control unit and, when the charging target device is in a fully charged state, stops an operation of displaying the charging state, and a delay unit that delays stopping the operation of the display unit that displays the charging state, for a previously set period of time, when the charging target device in the fully charged state is recharged.

A coupling channel noise canceling circuit includes a signal detecting unit, a gain setting unit, a cancel signal generating unit, and a noise canceling unit. The signal detecting unit detects a phase difference and a voltage difference between a broadcast RX signal and a noise cancel signal in a set mode. The gain setting unit outputs compensation gain values corresponding to the phase difference and the voltage difference from the signal detecting unit in the set mode. The cancel signal generating unit sets the compensation gain values from the gain setting unit as an amplification gain for amplification of a communication TX signal in the set mode, and amplifies the communication TX signal by a predetermined gain to generate the noise cancel signal in the set mode and an operation mode. The noise canceling unit cancels an interference noise from the broadcast RX signal by using the noise cancel signal from the cancel signal generating unit in the operation mode.
