A Digitalized Gyroscope System Based on a Modified Adaptive Control Method
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]
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-
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).
