| Abstract: | A PC plug-in data acquisition card is described with a sample rate up to 100 MSPS and 1 MByte on board storage in this paper. The method using two ADC driven alternataly by two complementary 50 MHz clock to form a 100MSPS sample rate is introduced. Some techniques such as how to get the two complementary clock, how to design the high speed and large storage circuit are also discussed in detail. |
