A Fast Background Frequency Calibration Based on Intermittent Frequency Locked Loop for the Super-Regenerative Receive

IEEE Access, 2022
The conventional phase-locked loops or frequency-locked loops should take time to calibrate the oscillator’s resonant frequency in a super-regenerative receiver (SRR) and severely disrupts the receiver’s operations.

Toward Tunable Magnetic Dirac Semimetals: Mn Doping of Cd3As2

Advanced Functional Materials, EarlyView.
Dilute magnetic doping of topological semimetals offers a pathway to tune the topological phase via time reversal symmetry breaking. This is achieved by alloying the Dirac semimetal Cd3As2 with Mn via molecular beam epitaxy. Magnetotransport measurements provide preliminary evidence of changes to the electronic structure consistent with the emergence ...

Output-jitter performance of second-order digital bang-bang phase-locked loops with nonaccumulative reference clock jitter

, 2011
Bang-bang phase-locked loops (BBPLLs) are inherently nonlinear systems due to the binary phase detector (BPD). While they are typically used for clock and data recovery, the ongoing trend toward digital loop implementations has resulted in several ...
