摘要

介绍了一种基于变压器的片上压控振荡器的多耦合LC油箱模型。采用多耦合LC槽的优点是可以对压控振荡器的等效LC槽进行Q因子增强、功耗低、幅值摆动好、调谐范围宽。作为示例，演示了采用0.18 μm BiCMOS工艺设计的具有低相位噪声或宽调谐范围的双lc -油箱的两个低功率Ku波段vco。

Transformer based multiple coupled LC tanks for on-chip VCO design and applications

A transformer based multiple coupled LC tanks model for on-chip VCO design is introduced. The merits of adoption multiple coupled LC tanks can be Q factor enhancement for the equivalent LC tank of VCO, low power consumption, better amplitude swing and broad tuning range can be obtained. As an illustration case two low power Ku band VCOs using dual LC-tanks with/without feedback designed using a 0.18 μm BiCMOS process for low phase noise or wide tuning range are demonstrated.
