Designing circular CMUT cells using CMUT biasing chart [PDF]
2012 IEEE International Ultrasonics Symposium, 2012 A very accurate equivalent circuit model for circular CMUT cell is recently proposed. As a consequence of this model, the operating characteristics of the cell is derived and presented as a biasing chart for CMUTs. We discuss these operating characteristics and show how the coupling coefficient can be derived from the model.
