摘　　要：在现有的CMOSRF工艺条件下,利用"切换式调谐"设计思想完成了宽带调谐的压控振荡器(VCO)的电路设计和版图设计,用CandenceSpectreRF软件进行了模拟。结果表明,该VCO在保证其它性能指标的同时,实现了宽的频率覆盖。This article designed a widetuningrange CMOS VoltageControlled Oscillator (VCO) circuit and its layout according to switched tuning technique under a given foundry process(Chartered 025μm CMOS RF Process). The design was simulated by Candence Spectre RF. The simulation results indicate that the VCO can cover wider tuning range and other performance also remains good.
