In this study, the oscillation signal stabilization and spurious tone suppression of a directly modulated optoelectronic oscillator (DM-OEO) are simultaneously achieved by modulating a laser with a low-frequency radio frequency (RF) signal. The laser

An all-digital phase-locked loop (ADPLL) with adaptive higher-order filter is proposed in this paper. The proposed ADPLL can select the first to third order of the loop filter by turning the IIR filter to adjust the system performance and attenuate i

In fractional phase-locked loop driven by ${\Sigma \Delta }$ modulators there can be spurious tones in the power spectral density (PSD) of output signals even if the PSDs of the sequences used to drive the frequency divider are spur-free. This is due

Fractional-N PLLs, particularly delta-sigma fractional-N PLLs, are some of the most popular integrated frequency synthesizers. They offer very fine grain frequency synthesis and find use in a wide range of applications such as LO synthesis, phase/fre

This paper reports on the design and implementation of high performance MEMS microphones. The main parameters defining microphone performance, i.e., sensitivity, acoustic overload level, and signal-to-noise ratio, have been extracted from an acoustic
