摘　　要：数模转换器可以将一个二进制数字量转换成与该数字量成正比的电压值,可应用于可编程电压源、波形发生器等。本文采用数字化技术,用FPGA实现了一个简单的一阶8位∑-Δ型DAC,只占用几个CLB。FPGA的速度和柔性的输出结构非常适合该DAC的实现。Digital to analog converters convert a binary number into a voltage directly proportional to the value of the binary number and they can be used for programmable voltage sources and waveform generators etc. In the paper,a simple one-order 8-bit Sigma-Delta DAC is implemented in a FPGA chip using digital technology and this application only takes a few CLBs.The speed and flexible output structure of the FPGAs make them suit for this application.
