64-Channel ultrasound transducer amplifier
In this paper we present a 64-channel ultrasound preamplifier device that is used to amplify and filter pulsed echo transducer signals sourced from a real time three dimensional (RT3DU) non-invasive ultrasound system. Schematics, simulation data, and layout for each of the broadband sub-circuit macros are described which include a high gain preamplifier, a linear output buffer, and bias circuits. This device was implemented using AMI Semiconductor's, 0.5 μm, double poly, triple level metal CMOS technology. The device floorplan, circuit schematics and layout, specifications and measured test data are presented.
