(ω), which we get by sweeping the modulation frequency,ω, of the heating laser at fixed power and measuring Δf0with the PLL and a second lock-in (see Supplementary Note3). We fit the measuredRf(ω) with Eq.2to extract the fit parameter\(\tau _T = R_{\mathrm{T}}C\)(i.e....
If both the input clock signals fail, an internal reference signal (RC_CLK) maintains the PLL at a nominal operating frequency until one of the input clock signals is restored whereby the loop can quickly re-establish phase lock. To determined validity, the input clock signals are sampled and...
Modelling and control of wind turbines are typically in a synchronous reference frame (d–qdomain) whose reference angle is provided by a PLL. Thus the dynamic characteristics of PLL greatly influence the response speed of wind farms, which mainly dominate their grid synchronisation to power system...
because the AOM output represents a drift-corrected Y value, the AD9548 output maintains frequency stability similar to that experienced while the 1 pps GPS signal was available. Then, should the GPS receiver return to a lock condition (identifying the end of holdover operation), the whole proce...

The figure also shows that Vccpll voltage regulator (VRM)212is designed to automatically maintain a desired voltage level Vccpll that supplies phase lock loop202. Whereas prior art VRMs operate by comparing an actual output voltage to a precise bandgap reference voltage, in contrast the present in...
