摘要

本工作提出了一种新的方法来重新配置体声波固体安装谐振器(BAW-SMR)滤波器的可行性，该方法是通过在并联谐振器上添加带晶体管的串联电容器，并用2to4解码器控制这些晶体管。该方法适用于W-CDMA (2.11-2.17 GHz)通信标准下的滤波器。实验结果表明，调谐范围为14MHz，而仿真的调谐范围为12MHz。

Controlling the bandwidth of Bulk Acoustic Wave filter using a decoder designed on 65nm process

This work presents the feasibility of a new method to reconfigure Bulk Acoustic Wave-Solidly Mounted Resonator (BAW-SMR) filters by adding capacitors in series with transistors to the shunt resonators and by controlling these transistors with a 2to4 decoder. This method is applied to filters operating in the W-CDMA (2.11–2.17 GHz) communication standard. Experimental results show a tuning range of 14MHz, whereas 12MHz of tuning range was achieved in the simulation.
