Abstract :
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.
