Introduction

By transmitting acoustic energy into the body and receiving and processing the returning reflections, ultrasound systems can generate images of internal organs and structures, map blood flow and tissue motion, and provide highly accurate blood velocity information.

Ultrasound systems include transducers, high voltage multiplexing, high voltage transmitters, transmit/receive switches, receive-path analog front end (AFE), beamformers, beamformed digital signal processing, display processing, and peripherals. The AFE includes a low noise amplifier (LNA); a variable gain amplifier (VGA); an antialias filter (AAF); and an analog-to-digital converter (ADC). There are two kinds of beamformers: digital beamformers and analog beamformers for different applications.
