Abstract

This thesis describes the design and realization of integrated ultrasound transceivers for carotid artery imaging and intracardiac echocardiography (ICE). The goal of this work is to investigate system- and circuit-level techniques to address requirements and implementation bottlenecks in these applications. Prototype chips are presented to demonstrate the effective of these techniques. The first prototype provides cable-count reduction and the capability to interface with a large-aperture transducer array for 3D carotid artery imaging. The second prototype is targeted at a 2D ICE probe, and features a novel bipolar high-voltage (HV) pulser, and an analog front-end with continuous time-gain compensation while achieving a superior noise efficiency factor.
