TL;DR: In this article, a 1.4-mm-diameter dual-ring transducer array using CMUT-on-CMOS technology on a front-end IC implemented in 0.35-μm CMOS process is presented.

TL;DR: Successful fabrication and performance evaluation of CMUT arrays for intravascular imaging on custom-designed CMOS receiver electronics from a commercial IC foundry and the CMUT-to-CMOS interconnect method reduced the parasitic capacitance by a factor of 200 when compared with a standard wire-bonding method.

TL;DR: Harmony generation in CMUTs with a time-domain model is analyzed and it is shown that for subharmonic ac excitation, although resistive and capacitive impedances result in a trade-off between input voltage and harmonic distortion for a desired pressure output, harmonic generation can be suppressed while increasing the Pa/V transmit sensitivity for proper series inductance and resistance feedback.

TL;DR: A large-signal, transient model has been developed to predict the output characteristics of a CMUT array operated in the non-collapse mode based on separation of the nonlinear electrostatic voltage-to-force relation and the linear acoustic array response.

TL;DR: In this paper, a test setup capable of real-time image data collection using dual-ring CMUT-on-CMOS arrays was presented, using an FPGA to control Tx/Rx element selection and data collection functions.
