Abstract

This work evaluates the microwave nonlinear properties of ferroelectric BSTO thin films by measuring the frequency response of several coplanar transmission lines and interdigital capacitor structures as a function of the applied electric field from 150 Hz to 40 GHz. We obtain the distributed nonlear capacitance C(Vdc). We also measure the harmonic generation at microwave frequencies in ferroeletric transmission lines. An accurate circuit model is used to obtain C(Vrt). Information about the tuning speed of the film is obtained from the comparison between the two capacitances. Characterization of this mechanism is also required to asess the spurious signal generation in ferroelectric-based devices.
