Veneer, Single-chip High-speed Data Acquisition System Research And Design

With the development of science and technology, the Digital Storage Oscilloscope, as a common instrument, will replace Analog Oscilloscope. At the mean time, the growing domestic requirement of DSO has urged researching tasks in this area. The single board, single chip data acquisition system, which is the core of DSO, tries to assemble the control circuits of data acquisition circuits into a single FPGA chip to make it suitable for portable DSOs. In this article we also discuss the design of random acquisition circuit, signal condition circuit, A/D circuit and so on. In each digital circuit, the simulating results are given. At end of the paper, some problems, which are encountered in designing, debugging, simulating process, are presented and the solutions to them are given.
