Realization of Multi-Channel, High-Speed Waveform Generator Based on FPGA

Abstract:

This paper introduces the design and realization of a multi-channel high-speed waveform generator based on FPGA, Which consists of the high-speed clock generator, the high-speed high-precision digital to analog converter, multi-stage pipeline accumulator and high-speed small signal conditioning. At last, it gives some simulation. The results show that the output signal type of this waveform generator is rich, and the maximum output frequency is 80MHz. The waveform generator can be used in the fields which require multi-channel high-speed signal, such as phased array radar.
