一款Q值与L值可相互独立调谐且低噪声的差分有源电感
A Differential Active Inductor with Low Noise and Mutually Independent Tuning of Quality Factor and Inductance
摘要
Abstract
A novel voltage controlled differential active inductor(VCDAI)with mutually independent tuning of quality factor(Q)and in-ductance(L)and low noise is proposed,which is mainly composed of a positive transconductor,a negative transconductor,an active ad-justable 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 re-sults 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 per-centage 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 4.48 nV/√Hz and 0.62 nV/√Hz,respectively.关键词
