Broadband suppression of phase-noise with cascaded phase-locked-loops for the generation of frequency ramps [PDF]
The generation of analogue frequency ramps with non-fractional phase-locked-loops (PLL) is a cost effective way of linearising varactor controlled oscillators (VCO).

Power-efficient time-to-digital converter for all-digital frequency locked loops
An 8-bit time-to-digital converter (TDC) for all-digital frequency-locked loops ispresented. The selected architecture uses a Vernier delay line where the commonlyused D flip-flops are replaced with a single enable transistor in the delay elements.This ...

Transfer function-based generalization of grid forming power synchronization loops
With the increasing penetration of inverter-based resources, grid forming control is expected to play a key role in stabilizing future grids. In these controllers, the power synchronization loop is in charge of synchronizing the inverter to the grid ...
