Inventors:

Roy W. Berquist - Toddville IA
Richard A. Freeman - Cedar Rapids IA
Robert A. Newgard - Central City IA

Assignee:

Rockwell Collins, Inc. - Cedar Rapids IA

International Classification:

H03L 100

US Classification:

331176, 331 18, 331 66, 331 25, 327105, 455260

Abstract:

An integrated frequency source with an integrated frequency standard and an integrated frequency synthesizer is disclosed. A voltage-controlled oscillator in the frequency standard is eliminated with a resulting improvement in phase noise. A reference frequency in the frequency standard is provided directly to the frequency synthesizer. The integrated frequency source is put on frequency over temperature by storing reference frequency errors over temperature in a lookup table, measuring the temperature, and calculating in a microprocessor synthesizer control data that offsets the synthesizer to compensate for reference frequency errors.

Assignee:

Rockwell Collins, Inc. - Cedar Rapids IA

International Classification:

H03B 1/00

US Classification:

331 74, 331 34

Abstract:

The present invention is an apparatus for efficiently providing an output frequency signal based upon an input voltage. The sampling voltage controlled oscillator of the present invention may include a voltage controlled oscillator coupled with sample and hold circuitry. The voltage controlled oscillator frequency of the sampling voltage controlled oscillator may be a lower frequency whereby the voltage controlled oscillator frequency is sampled by the sample and hold circuitry to derive a higher frequency signal. Advantageously, the overall power consumption of sampling voltage controlled oscillator may be less than conventional voltage controlled oscillators.

International Classification:

H04B 1/40

US Classification:

4551911, 455 77, 4551913, 455338

Abstract:

The present invention is directed to a highly-integrated MEMS-based miniaturized transceiver. The transceiver utilizes a low band front-end to direct sample low band signals and a high band front-end to translate high band signals that cannot be directly sampled to low band before low band front-end processing. The low band front-end comprises an array of High-Q MEMS (microelectromechanical systems)-based filters/resonators separated by isolation amplifiers in selectable cascade with narrower bandwidth filters. Dynamic tuning ability is provided through the isolation amplifiers and the sample frequency of the analog-to-digital converter. This architecture is amenable to monolithic fabrication. The input frequency range is scalable with analog-to-digital conversion sampling rate improvements. Re-utilization of filters is spatially efficient and cost effective.

US Classification:

375376, 375354, 375355

Abstract:

The present invention is an apparatus for determining the phase difference between a reference frequency signal and an input signal. The frequency sampling phase detector of the present invention may include a phase detector coupled with sample and hold circuitry. The frequency sampling phase detector of the present invention may reduce the frequency of an input signal suitable for proportional and linear phase detection by the phase detector. Advantageously, the frequency sampling phase detector of the present invention may reduce power consumption over conventional phase detectors in combination with frequency dividers.

Abstract:

The present invention is a Chip Scale Atomic Clock (CSAC)-enabled Time and Frequency Standard (CTFS) architecture. The CTFS architecture includes a microcontroller, a Time Compensated Crystal Oscillator (TCCO) circuit which is connected to the microcontroller, and a Chip Scale Atomic Clock (CSAC) which is connected to the microcontroller. The microcontroller is configured for selectively causing the CTFS to provide a TCCO circuit-based output frequency when the CTFS has not locked to a predetermined atomic resonance, and is further configured for causing the CTFS to provide a CSAC-based output frequency when the CTFS has locked to a predetermined atomic resonance.

International Classification:

H03B 5/30

US Classification:

331116M, 331154, 331109, 331183

Abstract:

The present invention is a method for reducing phase noise in oscillator signals. For example, the oscillator may be a low phase noise MEMS-based oscillator and may include a resonator (ex. —a MEMS resonator). Further, the resonator of the oscillator may be operated near a bifurcation point. Still further, the MEMS resonator may be parametrically pumped in such a way so as to redistribute the quadrature signal noise (ex. —phase noise) to in-phase noise (ex. —amplitude noise).

US Classification:

Abstract:

A communication system and a method for using an approximating frequency synthesizer with frequency correction by digital signal processing (DSP) means to provide a radio transmitter or receiver with rapid high resolution tuning capabilities. A user selects a frequency upon which he wishes to transmit or receive information. An approximating synthesizer is used to provide an RF injection frequency. A radio controller interprets the user selected frequency and determines the closet available approximating synthesizer frequency. The controller commands the approximating synthesizer to the determined available frequency and calculates the difference in the determined available frequency and the user selected frequency. The calculated difference or error is passed on to the DSP for correction during frequency mixing in a single or multiple step process.
