SDH系统STM-16速率级CMOS注入同步环形振荡器
Monolithical Integrated CMOS Injected Synchronized Ring VCO for SDH STM-16 Systems
摘要
Abstract
Oscillator IC technique is developed by combining injecting synchronization technique with a ring VCO.Using the technique,a novel 2.488GHz of monolithical integrated injected synchronized ring VCO (ISRVCO) is realized in a standard 0.25μm CMOS process.The ISRVCO is characterized by the following performances:-100dBc/Hz@1MHz at free running frequency,-91.7dBc/Hz@10kHz when injection is locked.With the 3.3V of power supply,the tuning range is 150MHz and the locking range is 100MHz with 50mVp-p signal injection.关键词
