【摘要】 提出了一款品质因数(Q)与电感值(L)可相互独立调谐和低噪声的新型压控差分有源电感(VCDAI),主要由正跨导器、负跨导器、有源可调反馈电阻、可变电容以及负阻产生模块构成。基于TSMC 0.18μm工艺和Candence Virtuoso设计工具，对VCDAI进行了电路仿真、版图绘制和后仿真。后仿真结果表明，在5.8 GHz的高频下，Q峰值可由527调节至1 822,调谐率为110%,而L值的变化率仅为3.5%;在5.1 GHz的高频下，L值可由97.7 nH调节到188.3 nH,调谐率为63%,而Q值的变化率仅为2.2%;在1 GHz和8 GHz下，有源电感的输入噪声分别为■和■。更多还原

【Abstract】 A novel voltage controlled differential active inductor(VCDAI)with mutually independent tuning of quality factor(Q)and inductance(L)and low noise is proposed, which is mainly composed of a positive transconductor, a negative transconductor, an active adjustable feedback resistance, a variable capacitance and a negative resistance generation module. Based on TSMC 0.18 μm process and Cadence Virtuoso design tool, circuit simulation, layout design and post-layout simulation are conducted. The post-layout simulation results show that at 5.8 GHz, the Q peak value can be adjusted from 527 to 1 822 with the tuning percentage of 110%,while the variation rate of L value is only 3.5%,at high frequencies of 5.1 GHz, the L value can be adjusted from 97.7 nH to 188.3 nH with the tuning percentage of 63%,while the variation rate of Q values is only 2.2%,and under 1 GHz and 8 GHz, the input noise of the active inductor is ■,respectively.更多还原
