The phase domain analysis confirms that a second-order subharmonically injection-locked phase-locked loop (SIPLL) can be stable even if the loop filter is composed of only a tiny capacitor. Thus, the area of the loop filter shrinks dramatically to realize an area-efficient SIPLL. Besides, a fast-converging correlation loop is used to calibrate the gain error of the digital-to-time converter in background by using a binary search algorithm. It ensures the initial output of the correlator close to the final one and is insensitive to process/supply/temperature variations. The chip is fabricated in a 40 nm process and occupies a core area of 0.0104 mm2. The converging time of the correlation loop is within 30μs. The power consumption is 3.19mW from a 1.1 V supply.論文使用權限: 不同意授權數位時間轉換器相關性迴路頻率合成器小數型鎖相迴路次諧波注入技術time-to-digital converter(DTC)correlation loopfrequency synthesizerfractional-N phase-locked loopsubharmonically injection-locked techniquethesis10.6342/NTU201602412
