Abstract: The present disclosure discloses an apparatus and method for monitoring performance of an integrated circuit. The apparatus includes a delay line, which receives a pulse signal. The delay line has a controllable, variable length and propagates the pulse signal through a set length. The apparatus also includes a comparator, which receives the propagated pulse signal from the delay line and a clock signal, the comparator being arranged to determine whether the received signal is received early or late. The apparatus also includes a feedback loop, which receives input from the comparator for dynamically increasing or decreasing the set length of the delay line in dependence of the determination by the comparator. The apparatus determines a speed of the integrated circuit based on a determination by the comparator that the signal from the delay line closely matches the clock signal.

Abstract: An energy harvesting circuit is based on a switch mode inductive DC-DC converter circuit. The inductor current is sensed and a duration of an on-time is controlled in dependence on the sensed inductor current. A duration of an overall switching period of the converter circuit is controlled in dependence on an on-time set by a first timing control circuit and input and output voltages. This converter circuit enables independent control of the on-time and a full period of a converter cycle. Very rapid switching can be avoided which can give rise to very high energy consumption. The full cycle period can be set to achieve a desired constant value of an input resistance of the DC-DC converter, and thereby maximize power transfer.

Abstract: A communication device is disclosed. The device may be in particular a radio transmitter and a receiver that can operate with low power consumption and with improved interference rejection, therefore particularly suitable for use in low-power communication systems, such as wireless sensor networks and wireless body area networks. In one aspect, multiple frequency tones (carriers) are used to carry information from the transmitter, such that a RF signal having multiple radio frequency components is produced and transmitted. In the receiver, an envelope detector is still the RF down-converter. After down-converting intermodulation components are extracted containing amplitude, phase and frequency information of the multiple radio frequency components. This allows the desired signal (the baseband information) to be distinguished from the carriers and unwanted interference.

Abstract: An antenna arrangement for transmitting energy is described. The antenna arrangement includes a planar array of two or more rectangular loop antennas, adapted to transmit energy at low frequencies via non-radiative resonant coupling and at high frequencies via radiative coupling. The low frequencies correspond to a wavelength with half of the wavelength being larger than the longest rectangular loop antenna dimension and the high frequencies correspond to a wavelength with half of the wavelength being approximately equal the longest rectangular loop antenna dimension. The antenna arrangement also includes a feeding network connected to the planar array, which includes a phase shifting means for providing a phase difference between signals at the high frequencies to be transmitted by different rectangular loop antennas of the planar array, whereby the amount of phase difference is related to the distance of the rectangular loop antennas to a focal point in the near-field of the planar array. The antenna arrangement also includes means adapted for distributing the signals applied to the feeding network.
