摘要:
基于TSMC 0.35 μm CMOS工艺,设计并实现了一种用于锁相环(PLL)频率合成器中的低相位噪声LC压控振荡器.这种压控振荡器采用互补交叉耦合差分结构,利用开关电容阵列技术增大频率调谐范围,并结合大滤波电容、二次谐波谐振滤波网络、开关电容阵列和偏置滤波网络来降低相位噪声.采用TSMC 0.35 μm CMOS工艺完成前仿真、版图设计与后仿真,芯片面积为1 285.3 μm×1 162.7 μm.流片测试结果显示,LC压控振荡器的频率调谐范围为1.558~2.065 GHz,调谐范围高达28%,中心频率处的相位噪声为-133.3 dBc/Hz@1 MHz,综合性能指数为-183.3 dBc/Hz.由此表明,所设计的压控振荡器具有比较优异的综合性能.
Abstract:
Based on TSMC 0.35 μm CMOS process, a fully integrated LC voltage controlled oscillator(VCO)used in phase lock loop(PLL)frequency synthesizer with low phase noise is designed and implemented. The LC VCO has a complementation cross-couple differential structure and adopts switched-capacitor technique to increase frequency tune range. Large filtering capacitance, second harmonic filtering network, switched-capacitor array and bias filter network are used to reduce phase noise. Simulation, layout design and post-simulation are completed by TSMC 0.35 μm CMOS process. The chip size is 1 285.3 μm × 1 162.7 μm. Chip testing results show that the frequency of the LC VCO can be tuned from 1.558 to 2.065 GHz. The tune range is 28%. In the center oscillation frequency, the phase noise of the LC VCO can achieve -133.3 dBc/Hz at 1 MHz, and the FOM(figure of merit)is -183.3 dBc/Hz. Thus, the overall performance of the designed VCO is good.
