Abstract: A system for simultaneously driving a plurality of antennas for transmission of an electromagnetic wave includes a first terminal, a second terminal, a first driver coupled to the first terminal, and a second driver coupled to the second terminal. The system includes a circuit configured to generate an indication of a phase difference between a first current through the first terminal and a second current through the second terminal. The system includes a control circuit configured to enable the first driver and the second driver to concurrently drive a first signal through the first terminal and a second signal through the second terminal, respectively, and configured to adjust a delay between the first signal and the second signal based on the indication of the phase difference and a predetermined target phase difference.

Abstract: In accordance with a first aspect of the present disclosure, a communication device is provided, comprising: a transmitter configured to transmit one or more radio frequency signal pulses; a detection unit configured to detect one or more load changes at a radio frequency interface occurring in response to the radio frequency signal pulses transmitted by the transmitter, wherein said load changes are indicative of the presence of an external communication device; a first clock generator comprising a free-running oscillator, wherein said first clock generator is configured to provide a clock signal to the transmitter and the detection unit while said transmitter transmits said radio frequency signal pulses and the detection unit detects said load changes. In accordance with a second aspect of the present disclosure, a corresponding method of operating a communication device is conceived.

Abstract: A low frequency (LF) antenna control circuit is disclosed. The LF antenna control circuit includes an antenna driver to drive an antenna, a current and phase measurement circuit to measure antenna current and signal phase, a modulator to modulate a signal to be transmitted via the antenna and a controller configured to drive the antenna through the antenna driver using a first fixed amplitude for a first time period, a second fixed amplitude for a second time period that is subsequent to the first time period and subsequent to the second time period, and subsequently, to drive the antenna using step up/down voltages based on the measured antenna current and signal phase. The signal included encoded bits of data to be transmitted.

Abstract: A power line communication system (200) comprising a first node (202) and a second node (204). The first node (202) comprises a second-node-connection-terminal (206); a first-node-transmission-module (208) that provides a first-node-output-signal (210) to the second-node-connection-terminal (206); and modulates the voltage level of the first-node-output-signal based on first-node-transmission-data. The second node (204) comprises a second-node-input-voltage-terminal (214) that is connected to the second-node-connection-terminal (206) of the first node (202) in order to receive the first-node-output-voltage-signal (210). The second node (204) is configured to use the first-node-output-voltage-signal (218) as a supply voltage. The second node (204) also includes a second-node-transmission-module (216) that: provides a second-node-current-signal (218) to the second-node-input-voltage-terminal (214) for transmission to the second-node-connection-terminal (206) of the first node (202); and modulates the current level of the second-node-current-signal (218) based on second-node-transmission-data. The second node (204) also includes a second-node-reception-module (222) that is configured to process the voltage level of the received first-node-output-signal (210) in order to demodulate the first-node-transmission-data. The first node (202) further comprises a first-node-reception-module (226) that processes the current level of the second-node-current-signal (218) received from the second node (204) at the second-node-connection-terminal (206) in order to demodulate the second-node-transmission-data.

Abstract: Embodiments of a multiphase clock generation device may include an input for feeding a reference clock, a clock generation unit adapted to generate phase-shifted clock signals from the reference clock, and a phase comparator unit functionally coupled with the clock generation unit. The phase comparator unit is adapted to measure a phase shift of the phase-shifted clock signals. The multiphase clock generation device includes a self-calibration unit that is functionally coupled with the clock generation unit. The calibration unit outputs a delay-calibration parameter to the clock generation unit. The clock generation unit is adapted to generate a multiphase clock signal out of the reference clock and the delay-calibration parameter.
