Analog PLLs have been well modeled by linear control theory. Starting from a well-defined model in the continuous-time domain, this article intro-duces a modeling and design method for a …

With the advent of the software radio and other modern digital devices, discrete-time phase-locked loops (DT-PLLs) are being implemented more than ever before. These modern …

A PLL is a feedback system that includes a VCO, phase detector, and low pass filter within its loop. Its purpose is to force the VCO to replicate and track the frequency and phase at the …

In this paper a discrete-time, linear, periodically time-variant integer- PLL model for jitter analysis is proposed, which accounts for the periodically time-varying effect of noise injected into the …

In this series of tutorials on discrete-time PLLs we will be focusing on Phase-Locked Loops that can be implemented in discrete-time signal proessors such as FPGAs, DSPs and of course, …

In this paper a discrete-time, linear, cyclostationary PLL model for jitter analysis is proposed, which accounts for the cyclostationary nature of noise injected into the loop at various PLL …

Nevertheless, as proven in this paper, PLLs based on the SLF can be modeled accurately as discrete-time LTI sys-tems. This paper derives such an LTI model and demonstrates how it …

2014年10月29日 · This paper presents a discrete phase-locked loop (PLL) method aimed to provide an estimation of the angular frequency, and both the positive and negative sequences …
