| Abstract: | A high-speed data acquisition system with two channels is described in this paper, which is designed by TTL logic completely and with a sample rate up to 100MSPS. The system has advantages of less kinds and low dissipation of power, simple circuit design and convenient circuit debug. A dynamic measurement is taken and the results show that the ENOB of the system is more than 7 bits. |
