چکیده

A transmitter front-end IC for ultrasound medical imaging applications is implemented using 30-V 0.18-mm Bipolar/CMOS/DMOS process. The proposed ultrasound transmitter front-end, consisting of voltage level-shifters and an output driver, achieves high integration and maintains good reliability while generating a 33 ns output pulse signal in order to drive a large capacitive load, which represents the equivalent capacitance of the capacitive micromachined ultrasound transducer device. The proposed high-frequency transmitter achieves a delay of less than 20 ns at 30 Vp–p output voltage while successfully driving a capacitive load of 44 pF and consumes an area of 0.34 mm. & 2013 Elsevier Ltd.

Analog Front-end Design for Wearable Ultrasound Systems

This project aims to provide a highly flexible platform for 3D ultrasound imaging. Figure 1 presents the system architecture. The CMUT device is flip-chip bonded to the supporting electronic circuits, which eliminates the cables. As a result, the channel count of the imaging system is increased, and the capacitive loading due to cables is greatly reduced. The transmitters in the system are reco...
