A Low Mismatch Current Charge Pump Applied to Phase-Locked Loops [PDF]

Micromachines
This paper presents a charge pump circuit with a wide output range and low current mismatch applied to phase-locked loops. In this designed structure, T-shaped analog switches are adopted to suppress the non-ideal effects of clock feedthrough, switching ...

Structural Resemblance Between Droop Controllers and Phase-Locked Loops [PDF]

IEEE Access, 2016
It is well known that droop control is fundamental to the operation of power systems and now the parallel operation of inverters, while phase-locked loops (PLLs) are widely adopted in modern electrical engineering.

Improvement of GNSS Carrier Phase Accuracy Using MEMS Accelerometer-Aided Phase-Locked Loops for Earthquake Monitoring [PDF]

Micromachines, 2017
When strong earthquake occurs, global navigation satellite systems (GNSS) measurement errors increase significantly. Combined strategies of GNSS/accelerometer data can estimate better precision in displacement, but are of no help to carrier phase ...

Non-linear behaviour of charge-pump phase-locked loops [PDF]

Advances in Radio Science, 2010
The analysis of the mixed analogue and digital structure of charge-pump phase-locked loops (CP-PLL) is a challenge in modelling and simulation. In most cases the system is designed and characterized using its continuous linear model or its discrete ...
