High frequency low noise phase-frequency detector and phase noise reduction method and apparatus

The present invention discloses a new type of extremely low-noise phase-frequency detector (PFD) 500, broadband from DC to multi-GHz RF frequencies for PLL synthesizer applications. Free of any feedback mechanisms, thus inherently fast, it operates close to transition frequency fT of IC processes or frequency limits of discrete mixers. The PFD 500 utilizes complex SSB conversion in both the in-phase and quadrature arms, delaying the in-phase arm in 530, beating the delayed signal 124 with the un-delayed quadrature signal 122 in mixer 126. The output 128 contains both the frequency difference and the phase difference information between the two signals 118 and 520, providing both the frequency-discrimination (FD) and the phase detection (PD) functions. Utilizing standard mixers the PFD 500 can achieve superior CNRs of 180 dBc / Hz at multi-GHz RF. Additionally, utilizing the FD / FM demodulation capability, the present invention improves phase noise of various signals and linearity of FM modulators.

Printed circuit board memory module with embedded passive components

A memory module includes a plurality of memory components mounted on a printed circuit board, and a plurality of passive components embedded within the board directly underneath the memory components to minimize the space occupied by the passive components and the lengths of the required conductive traces. The passive components and the memory components are connected by conductor-filled vias between the contacts of the embedded components and the memory components mounted above them on the board surface. The passive components may be thick film resistors, either series damping resistors or differential damping resistors. By embedding the resistors directly beneath the memory components, there is enough space on the board to provide a set of termination resistors for each of the several memory components on the board, thereby eliminating the need for a single resistor to be shared by two or more memory components, resulting in more precise output signals.

Modem with pilot symbol synchronization

A modem, or a communication system, in its transmission section, has signal-formatting circuitry followed by circuitry for insertion of a sequence of pilot symbols into a sequence of data symbols outputted by the formatting circuitry. Placement of the insertion circuitry after the formatting circuitry permits a variety of formatting options without effecting the sequence of pilot symbols that serves as a time reference useful in detection of a signal transmitted by the modem. The reception section of the modem is equipped correspondingly to process a received composite signal of data symbols having a prescribed format and a sequence of pilot symbols. The reception section extracts the sequence of pilot symbols from the composite signal, and employs the pilot symbols to develop a time base for operation of circuitry for decoding the format of the received composite signal to extract data from the composite signal.

Oscillating fluid power generator

ActiveUS20070297903A1Reduce purchasing costsIncrease technical and economic viabilityEngine fuctionsWorking fluid for enginesOscillating flowEngineering
A system and method for harvesting the kinetic energy of a fluid flow for power generation with a vertically oriented, aerodynamic wing structure comprising one or more airfoil elements pivotably attached to a mast. When activated by the moving fluid stream, the wing structure oscillates back and forth, generating lift first in one direction then in the opposite direction. This oscillating movement is converted to unidirectional rotational movement in order to provide motive power to an electricity generator. Unlike other oscillating devices, this device is designed to harvest the maximum aerodynamic lift forces available for a given oscillation cycle. Because the system is not subjected to the same intense forces and stresses as turbine systems, it can be constructed less expensively, reducing the cost of electricity generation. The system can be grouped in more compact clusters, be less evident in the landscape, and present reduced risk to avian species.

Zero IF complex quadrature frequency discriminator and FM demodulator

A frequency discriminators (FD) and frequency modulation (FM) demodulators, utilizing single sideband (SSB) complex conversion directly to zero IF, suitable for direct demodulation at high frequencies of analog FM or digital FSK modulated signals, as well as for high speed frequency discrimination (or frequency comparison) in applications such as frequency acquisition in frequency synthesizers. The complex SSB down-converter consists of a quad of mixers and quadrature splitters in both the signal path and local oscillator (LO) path. Each mixer receives both the signal and the LO, each either in-phase or quadrature. The outputs of mixers are combined in pairs, to produce the SSB in-phase (I) baseband signal and the SSB quadrature (Q) baseband signal. Both I and Q signals are then delayed, each multiplied by un-delayed version of the other one. The multiplication products are summed together, to produce an FD error signal, or an FM demodulated signal at the output. The delay time can be dynamically controlled, in order to set the FD frequency range or to adjust the gain of the FM demodulator.
