  • Patent number: 9490965
    Abstract: Embodiments of the invention are generally directed to simultaneous transmission of clock and bidirectional data over a communication channel. An embodiment of a transmitting device includes a modulator to generate a modulated signal including a clock signal and a data signal, the clock signal being modulated by a first signal edge of the modulated signal and the data signal being modulated by a position of a second signal edge of the modulated signal; a driver to drive the modulated signal on a communication channel; an echo canceller to subtract reflected signals on the communication channel; and a data recovery module to recover a signal received on the communication channel, the received signal being encoded by Return-to-Zero (RZ) encoding, the signal being received simultaneously with driving the modulated signal on the communication channel.

  • Patent number: 9065892
    Abstract: A receiver, a mobile terminal including the receiver, and a method of disposing the receiver on the mobile terminal are disclosed. The mobile terminal including: a receiver including: a casing including walls and an inner space defined at least partially by the walls, a diaphragm driving unit disposed in the casing, a diaphragm including a central region disposed in the casing, a projection unit extending from the casing, the projection unit including walls and a receiver hole disposed in one of the walls, and an audio path defined within the casing walls and the projection unit walls; and a Printed Circuit Board (PCB) including a cutout along an edge. The diaphragm may be disposed between the diaphragm driving unit and the inner space, and the audio path extends from the diaphragm central region through the inner space to the receiver hole. The receiver may be disposed in the cutout in the PCB.

  • Patent number: 7570105
    Abstract: A charge pump circuit includes switch circuit modules and current modules. The number of switch circuit modules that are coupled to receive current from one of the current modules is variable. The output current of the charge pump circuit increases as more of the switch circuit modules are coupled to receive current from the current modules. The net on-resistance of the switch circuit modules decreases as more of the switch circuit modules are coupled to receive current from the current modules. Charge coupling caused by the net parasitic gate-to-drain capacitance of switching transistors in the switch circuit modules is reduced at smaller output current settings of the charge pump circuit.
