Analysis of mutual acoustic coupling in CMUT arrays using an accurate lumped element nonlinear equivalent circuit model
(2012)We use an accurate nonlinear equivalent circuit model to analyze CMUT arrays with multiple cells, where every cell in the array is coupled to other cells at their acoustic terminals through a mutual radiation impedance ... -
An equivalent circuit for collapse operation mode of CMUTs
(IEEE, 2010)Collapse mode of operation of the capacitive mi-cromachined ultrasonic transducers (CMUTs) was shown to be a very effective way for achieving high output pressures. However, no accurate model exists for understanding the ... -
An equivalent circuit model for transmitting capacitive micromachined ultrasonic transducers in collapse mode
(IEEE, 2011)The collapse mode of operation of capacitive micromachined ultrasonic transducers (CMUTs) was shown to be a very effective way to achieve high output pressures. However, no accurate analytical or equivalent circuit model ... -
Equivalent circuit-based analysis of CMUT cell dynamics in arrays
(IEEE, 2013)Capacitive micromachined ultrasonic transducers (CMUTs) are usually composed of large arrays of closely packed cells. In this work, we use an equivalent circuit model to analyze CMUT arrays with multiple cells. We study ... -
Nonlinear equivalent circuit model for circular CMUTs in uncollapsed and collapsed mode
(IEEE, 2012)An equivalent electrical circuit model valid for collapsed mode operation of CMUT is described. The across and through variables of the circuit model are chosen to be rms force and rms displacement over the surface of the ... -
Optimizing CMUT geometry for high power
(IEEE, 2010)Capacitive micromachined ultrasonic transducers (CMUTs) have demonstratedvarious advantages over piezoelectric transducers. However, current CMUT designsproduce low output pressures with high harmonic distortions. Optimizing ...
