Butterworth-van dyke circuit

WebJan 16, 2024 · The conversion process is analyzed by applying an equivalent circuit model that relates device-level parameters to overall figures of merit for conversion efficiency η and added noise N. These can be further enhanced by proper impedance matching of the transducer to an input microwave transmission line. Webwaves to electrical currents [6]. The Butterworth Van-Dyke model (BVD) is applied in the analysis conducted in this paper. This is a commonly used model for different SAW filters, oscillators and sensors [5, 7]. The model utilizes a circuit with two parallel branches, the R-L-C branch and C-branch as shown in Figure-1.
