基于FPGA的B超收发前端电路设计

The design of the Transmit/Receive front end of the B mode ultrasonic instruments base on FPGA

本文介绍一种基于FPGA的B超前端发射和回波接收放大部分的电路设计方案。FPGA主要用于对发射高压多路电子开关、接收模拟矩阵电子开关的控制和数字化发射延时聚焦等控制的实现。

This article introduce the design of the Transmit/Receive front end of the B mode ultrasonic instruments base on FPGA.In this design, the FPGA chip mainly used to control the multi-switchs, the analog matrix electron swiths and the digital fire-delay focusing etc.
