摘要
采用0.18 m 6金属层标准数字CMOS技术,设计并实现了适用于SDH (STM-64)和SONET (OC-192)光接收机数据时钟恢复架构的10 GHz全集成LC vco。对三种不同变容管版本的注入环型和交叉耦合型LC压控振荡器的性能进行了测试。所有压控振荡器在1.8 V电源下均具有合理的相位噪声性能和调谐特性。
10 GHz fully integrated LC VCOs suitable for data clock recovery architectures in optical receivers of SDH (STM-64) and SONET (OC-192) were designed and implemented in a 0.18 ¿m 6-metal-layer standard digital CMOS technology. The performance of injection ring type and cross-coupled type LC VCOs with three different varactor versions have been tested. All VCOs present reasonable phase noise performance and tuning characteristics under 1.8 V power supply.
