A 3-3.7GHz Time-Difference Controlled Digital Fractional-N PLL With a High-Gain Time Amplifier for IoT Applications

open access: yesIEEE Access, 2022
This paper presents analyses of jitter and reference spur of a digital PLL using a phase-frequency detector (PFD) and a time amplifier (TA). In the PFD-TA PLL, the TA amplifies a phase error between a reference clock and a divided feedback clock.

Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat

open access: yesIntegrative Zoology, EarlyView.
After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...
