The performance of analogue phase-locked loops (PLLs) has steadily improved with operating frequencies extending to 8GHz and beyond. Recently, digital PLLs based on direct digital synthesis (DDS) have ...
The purpose of a phase locked loop (PLL) is to generate a frequency and phase-locked output oscillation signal. To achieve this goal, prior art essentially functioned ...
A resolver is a sensor that estimates the angle of a rotating shaft, such as the shaft of an electrical motor used in automotive traction inverter applications. To obtain a digital representation of ...
In this paper an All Digital phase locked loop is proposed. This PLL can accomplish faster phase lock. Additionally, the functions of frequency comparator and phase detector have been improved and are ...
Optical frequency comb synthesizers have represented a revolutionary approach to frequency metrology, providing a grid of frequency references for any laser emitting within their spectral coverage.
