IEEE International Solid-State Circuits Conference, 2022
To pursue the ever-growing trend in mobile data-rates, modern transceivers exploit carrier aggregation and high-order modulations, at the price of calling for ultra-low jitter (below 100fs) and frequency-agile local oscillators.

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2021
This brief presents a 2.4-GHz crystal-less GMSK/GFSK phase-tracking receiver (PTRX) that employs a multiphase bang-bang PLL (BBPLL) as an auxiliary loop to perform multibit oversampled demodulation.

A 20-GHz PLL With 20.9-fs Random Jitter
IEEE Journal of Solid-State Circuits, 2023This article describes an integer- $N$ phase-locked loop (PLL) that incorporates a phase detector sampling both the rising and falling edges of the reference clock. The circuit also uses a new retiming method in the feedback divider.

The phase-locked loop (PLL) will have a negative impact on the stability of doubly fed induction generators (DFIG) system under inductive weak grid. Some PLL-less methods have been presented to remove the PLL such as switching the synchronous reference ...

On Transient Instability Mechanism of PLL-Based VSC Connected to a Weak Grid
IEEE transactions on industrial electronics (1982. Print), 2023This article analyzes the transient process of phase-locked loop (PLL) based grid-connected voltage source converters (VSCs) under large disturbances by modeling the PLL dynamic model and active power loop model.
