Talk Title: Frequency Agile Circuits Based on Thin Film Ferroelectrics
Series: Integrated Systems Seminar Series
Abstract: My talk is on the design of frequency agile circuits based on thin film ferroelectrics. Central to this work is the use of thin film barium strontium titanate (BST), a low loss, high dielectric constant field dependent material. The electric field dependence of BST is used to design tunable RF and microwave devices and components. Other applications such as linearization of power amplifiers will also be discussed. Another important characteristic of BST is its dc electric field induced piezoelectric and electrostrictive effects. These properties can be utilized to design intrinsically switchable film bulk acoustic wave resonators (FBARs) and FBAR filters. Ferroelectric based filter banks can make it possible to reduce size and power consumption of conventional filter banks employed in multi-standard and frequency agile radios. Recent results for intrinsically switchable BST bulk acoustic wave resonators and filters will be presented.
