摘要： A ferroelectric varactor suitable for capacitive shunt switching is disclosed. High resistivity silicon with a SiO2 layer and a patterned metallic layer deposited on top is used as the substrate. A ferroelectric thin-film layer deposited on the substrate is used for the implementation of the varactor. A top metal electrode is deposited on the ferroelectric thin-film layer forming a CPW transmission line. By using the capacitance formed by the large area ground conductors in the top metal electrode and bottom metallic layer, a series connection of the ferroelectric varactor with the large capacitor defined by the ground conductors is created. The large capacitor acts as a short to ground, eliminating the need for vias. The concept of switching ON and OFF state is based on the dielectric tunability of the ferroelectric thin-films. At 0 V, the varactor has the highest capacitance value, resulting in the signal to be shunted to ground, thus isolating the output from the input. This results in the OFF state of the switch. By applying a small voltage to the center conductor of the CPW, the varactor's capacitance can be reduced allowing the signal to be transmitted through resulting in the ON state of the device. Such a varactor shunt switch eliminates majority of problems plaguing the RF MEMS shunt switches.
摘要翻译：公开了一种适用于电容分流开关的铁电变容二极管。使用具有SiO 2层的高电阻率硅和沉积在顶部的图案化金属层作为衬底。沉积在基板上的铁电薄膜层用于实现变容二极管。顶层金属电极沉积在形成CPW传输线的铁电薄膜层上。通过使用由顶部金属电极和底部金属层中的大面积接地导体形成的电容，产生铁电变容二极管与由接地导体限定的大电容器的串联连接。大电容器作为短路对齐，不需要通孔。导通和断开状态的概念基于铁电薄膜的介电可调性。在0 V时，变容二极管具有最高的电容值，导致信号被分流到地，从而将输出与输入隔离。这导致开关的OFF状态。通过向CPW的中心导体施加小电压，可以减小变容二极管的电容，从而允许通过导致器件的导通状态来传输信号。这种变容二极管分流开关消除了困扰RF MEMS分流开关的大部分问题。
