A Digitalized Gyroscope System Based on a Modified Adaptive Control Method

open access: yesSensors, 2016
In this work we investigate the possibility of applying the adaptive control algorithm to Micro-Electro-Mechanical System (MEMS) gyroscopes. Through comparing the gyroscope working conditions with the reference model, the adaptive control method can ...

A design methodology to enable sampling PLLs to synthesise fractional-N frequencies [PDF]

open access: yes, 2011
A novel design methodology is proposed to enable sampling phase-locked loops (SPLL) to synthesise fractional-N frequencies. To date, SPLL can only generate integer-N frequencies.

Nonlinearity-Induced Spur Analysis in Fractional-N Synthesizers With ΔΣ Quantization Cancellation

open access: yesIEEE Open Journal of the Solid-State Circuits Society
A fractional-N frequency synthesizer with low total jitter [e.g., <50fsrms, accounting for both phase noise (PN) and spurs] is essential for enabling the emerging 5G/6G and other high-speed wireless communication standards (e.g., WiFi-6/7).

Fully differential electro-mechanical phase locked loop sensor circuit [PDF]

open access: yes, 2013
Embedding a micro-machined sensing element in a closed loop, force feedback system is a technique commonly used to realise high performance MEMS (micro-electro-mechanical systems) sensors due to the advantages of better linearity, increased dynamic range

Exact lock-in range for classical phase-locked loops

open access: yes, 2021
Phase-locked loops (PLLs) are are widely used in various applications: Wireless communications, GPS navigation, gyroscope systems, computer architectures, electrical grids, and others. PLLs are inherently non-linear, but in engineering practice, they are
