Single-chip surface micromachined integrated gyroscope with 50°/h Allan deviation

IEEE Journal of Solid-State Circuits, 2002
The design principles of a mass-produced surface micromachined gyroscope are described. The device is integrated on a single 3 mm/spl times/3 mm chip with a 3-/spl mu/m BiCMOS process. It has a 4-/spl mu/m-thick polysilicon structure, 5-V 6-mA supply, 12.5-mV//spl deg//S sensitivity, 10 000:1 dynamic range, 30 000-gee shock survival, and -55/spl deg/C ...

An Algorithm to Estimate the Power Spectral Density From Allan Deviation

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control
Complex architectures for wireless communications, digital electronics, and space-based navigation interlink several oscillator-based devices such as clocks, transponders, and synthesizers. Estimators characterizing their stability are critical for addressing the impact of random fluctuations (noise) on the overall system performance.

Allan deviation measurements of a cryogenic all-sapphire Fabry-Perot reference cavity

Proceedings of 20th Biennial Conference on Precision Electromagnetic Measurements, 2002
An all-sapphire Fabry-Perot cavity is temperature controlled in a cryogenic (/spl sim/5 K) environment. The cavity is used as a frequency reference to stabilise the output of a diode pumped Nd:YAG laser. The expected stability is discussed and Allan Deviation measurements presented.

Measuring accelerometer dynamic range from seismic data using Allan deviation

Geophysical Prospecting, 2018
ABSTRACTWe propose a new approach for calculating the dynamic range of an accelerometer based on an Allan deviation analysis of production seismic data. This test is intended as a field audit technique and does not require an unconditioned dataset from a low‐noise environment.

A 46μW, 8.2MHz self-threshold-tracking differential relaxation oscillator with 7.66psrms period jitter and 1.56ppm allan deviation floor

2018 IEEE Custom Integrated Circuits Conference (CICC), 2018
This paper presents an 8.2MHz relaxation oscillator with swing boosting and self threshold tracking, designed to improve both period jitter and frequency stability. A self-threshold-tracking loop ensures the switching threshold is kept in a constant, reducing the frequency uncertainty from process, temperature and supply voltage variations. Implemented

A Mode-Matched Silicon-Yaw Tuning-Fork Gyroscope With Subdegree-Per-Hour Allan Deviation Bias Instability

Journal of Microelectromechanical Systems, 2008
In this paper, we report on the design, fabrication, and characterization of an in-plane mode-matched tuning-fork gyroscope (M2-TFG). The M2-TFG uses two high-quality-factor (Q) resonant flexural modes of a single crystalline silicon mi- crostructure to detect angular rate about the normal axis.

The Resonating Star Gyroscope: A Novel Multiple-Shell Silicon Gyroscope With Sub-5 deg/hr Allan Deviation Bias Instability

IEEE Sensors Journal, 2009
We report on the design, fabrication and characterization of a novel multiple-shell silicon vibratory microgyroscope. The resonating star gyroscope (RSG) is formed as a merged superposition of two square shells, yielding in-plane flexural modes that are utilized to sense rotation along the normal axis.

Allan deviation characterization of an optical-frequency-division-stabilized, hybrid-packaged microcomb

CLEO 2025
A dispersive-wave-tunable microcomb is hybrid packaged with a III-V DFB pump laser. The Allan deviation of the repetition rate is characterized when stabilized to a Fabry–Pérot cavity, using optical frequency division.

Use of the allan deviation and linear prediction for the determination of the uncertainty on time calibrations against predicted timescales

IEEE Transactions on Instrumentation and Measurement, 2003
In this paper, two linear prediction algorithms and the Allan deviation are used to determine the uncertainty on time calibrations performed against predicted timescales. The proposed algorithms are shown to be close to optimal and have the advantage of bounding the timescale prediction error without requiring a noise model of the timescale process.
