[ 1 ] - طراحی PLL دو حلقه ای مبتنی بر آشکارسازی فاز پنجره‌ای با سرعت قفل بالا، توان مصرفی و اسپور مرجع پایین

In this paper, a dual loop PLL with short locking time, low power consumption and low reference spur is presented. The output frequency and reference frequency of the designed circuit are 3.2 GHz and 50 MHz, respectively, aimed to WiMAX applications. In the proposed circuit in locked state, some parts of the circuit could be powered off, to reduce overall power consumption. Phase detection in t...
