低损耗衬底上实现无源低通滤波器(英文)
A Passive Low-Pass Filter on Low-Loss Substrate
【摘要】 分析比较了不同种类衬底上无源器件(片上电感和电容)的损耗机理,在OPS(氧化多孔硅)和HR(高阻硅)低损耗衬底上分别实现了片上低通滤波器.为了研究衬底损耗,设计了平面螺旋电感,其Q值在两种衬底上的仿真结果都超过了20.在OPS衬底上的低通滤波器实测-3dB带宽为2.9GHz,通带插入损耗在500MHz为0.87dB;在HR衬底上的低通滤波器实测-3dB带宽为2.3GHz,通带插入损耗在500MHz为0.42dB.
【Abstract】 The loss mechanisms of different passive devices (on-chip inductors and capacitors) on different substrates are analyzed and compared.OPS (oxidized porous silicon) and HR (high-resistivity) substrates are used as low-loss substrates for on-chip planar LPF (low pass filter) fabrication.For the study of substrate loss,a planar coil inductor is also designed.Simulation results show that Q (the quality factor) of the inductor on both substrates is over 20.Measurements of the LPF on OPS substrate give a -3dB bandwidth of 2.9GHz and a midband insertion loss of 0.87dB at 500MHz.The LPF on HR substrate gives a -3dB bandwidth of 2.3GHz and a midband insertion loss of 0.42dB at 500MHz.
【Key words】 LC low-pass filter; low-loss substrate; on-chip inductor; RF;
