Publication number: 20200373927Abstract: A control system method and apparatus that minimizes the difference between multiple state-derived signals, with application to frequency synthesis, is described. Existing Alias-Locked Loops (ALLs) use digital samplers in the feedback path to achieve a wide frequency lock range for high speed frequency synthesis, at the cost of one additional reference clock, compared to a Phase-Locked Loop (PLL). We propose the differential alias-locked loop (D-ALL) circuit architecture which uses only one reference clock input. In this D-ALL synthesizer architecture, two frequencies are derived from the voltage-controlled oscillator (VCO) output and are compared as the two inputs to the phase frequency detector (PFD). In contrast, a PLL or an ALL has a reference clock as one PFD input and a frequency derived from the VCO output as the other PFD input.Type: ApplicationFiled: May 25, 2020Publication date: November 26, 2020Inventors: Jinghang Liang, Duncan George Elliott

Patent number: 9614616Abstract: A correlation optical time domain reflectometer (OTDR) provides a correlation sequence that is continuously transmitted along a fiber for testing the fiber for anomalies. Such continuous transmission can result in beat noise that degrades the quality of the measured returns. In this regard, each sample is composed of backscatter returns from many points along the fiber that arrive at the OTDR at the same time. When a subset of these returns have frequency differences that appear in the passband of the OTDR receiver, the constructive and destructive interference of these returns at the OTDR receiver can cause significant low-frequency beat noise in the OTDR signal. An optical transmitter is configured to transmit the correlation sequence through the fiber using a wideband optical signal such that the beat noise is suppressed within the passband of the OTDR receiver, thereby improving the quality of the returns measured by the OTDR.Type: GrantFiled: June 19, 2013Date of Patent: April 4, 2017Assignee: ADTRAN, INC.Inventors: Daniel M.

Patent number: 8502317Abstract: A level shifter circuit for integrated circuits has one or more inputs that operate in a first voltage domain, and a signal output that operates in a second voltage domain. In some embodiments, the level shifter circuit receives two complementary input signals. The level shifter uses cross-coupled PMOS transistors with drain-bulk breakdown voltage less than the gate-oxide breakdown voltage of high-voltage PMOS transistors to prevent gate-oxide breakdown caused by sub-threshold leakage of auxiliary high-voltage PMOS transistors in the off state. Permanent gate-oxide breakdown is prevented through non-permanent sub-nanoamp drain-bulk junction breakdown. The level shifter circuit has the advantages of small circuit size and low static power consumption.Type: GrantFiled: February 7, 2010Date of Patent: August 6, 2013Inventors: Leendert Jan van den Berg, Duncan George Elliott

Patent number: 8462574Abstract: A high-density dynamic memory device with compact sense amplifier circuit is described. The memory device achieves high density through the use of a compact sense amplifier circuit that employs a single transistor to sense stored dynamic data. Functionality of the device is enabled by an architecture and method of operation that support a compact sense amplifier circuit. Enabling techniques include sequential sensing of memory columns, a two-pass write operation, a two-step refresh operation, a reference scheme that uses reference data stored in regular memory cells, and the application of digital signal processing to determine sensed data and cancel crosstalk noise.Type: GrantFiled: August 26, 2011Date of Patent: June 11, 2013Inventors: Kristopher Chad Breen, Duncan George Elliott

Patent number: 8359668Abstract: An improved traction sweatband includes a flexible collar for fitting onto the head of a wearer. The front of the collar has at least one aperture formed therein. The aperture or apertures each have a circumferential edge extending completely around the aperture. A flexible resilient sheet or sheets are mounted to the back surface of the collar so as to cover each aperture in the front of the collar. Each resilient sheet is mounted around the circumferential edge of its corresponding aperture. The mounting of the sheet to the circumferential edge is adapted so as to draw the sheet against the circumferential edge and so as to urge the sheet into the aperture to thereby bow the sheet into and across the aperture.Type: GrantFiled: February 5, 2010Date of Patent: January 29, 2013Inventor: Vernal George Elliott

Patent number: 7936192Abstract: A frequency synthesis phase-locked loop architecture using a regenerative sampling latch is described. The frequency divider typically employed in the feedback path of a frequency synthesis phase-locked loop is replaced by a regenerative sampling latch with a binary output. The regenerative sampling latch subsamples the frequency synthesizer output to produce a low-frequency aliased signal that can be processed further or directly used to lock the phase-locked loop. This architecture is referred to as an alias-locked loop. The relaxed constraints on the regenerative sampling latch make it possible to create high-speed frequency synthesizer phase-locked loops without the suffering the limitations imposed by traditional dividers connected directly to the oscillator output.Type: GrantFiled: May 15, 2009Date of Patent: May 3, 2011Inventors: Leendert Jan van den Berg, Duncan George Elliott
