Optimization of phase-locked loop circuits via geometric programming
Phase-locked loop circuit geometric programming frequency phase lock loop
2015/8/11
We describe the global optimization of phase-locked loop (PLL) circuits using geometric programming (GP). Equations for the jitter, frequency range, and power of the PLL are presented in GP form. An a...
Stability Analysis of a Closed-Loop Control for a Pulse Width Modulated DC Motor Drive
pulse width modulation (PWM) DC drive stability analysis
2009/7/28
In this paper, the effect of the variation of amplitude and the chopping period of a PWM signal on the stability of a closed-loop control for a DC motor drive is investigated. First, the entire system...

a Ka Band PLL DRO oscillator the dielectric resonator the active component
2010/12/6
This paper describes the design and fabrication of a Ka Band PLL DRO having a fundamental oscillation frequency of 19.250 GHz, used as local oscillator in the low-noise block of a down converter...
An Improved Decision Feedback Loop for Optical Communications
Decision Feedback Loop Optical Communications
2010/7/16
Based on the structure proposed in [1] and [2],two new types of parallel decision feedback loops are presented. Efforts are made to secure the data transition and relax the delay limitation for the in...
