Design and Characterization of a MEMS Varactor
Veröffentlicht in 2011
The tunable capacitor (variable capacitor) is one of the most important and components in filters, Phase shifters, VCO etc. A tunable capacitor can also be built using electro – thermal actuating mechanism. Compared to electro static, tunable capacitors actuated by thermal actuators have several advantages like lower driving voltages. The performance of thermal actuator becomes a key factor for performance of a tunable capacitor can provide larger forces and is also easier to control.
Four thermal actuators are employed to design a varactor (variable capacitor). Structural modeling has been done using COMSOL and the results are presented.
