Design of high-speed sampling circuits

As high-speed signal sampling is not easy to achieve and sampled high-speed data is not easy to accept or control, two methods of high-speed sampling clock generation and clock distribution are given relating to practical application. Two ways of high-speed data deceleration are introduced, namely the hardware multiplexer transition method and the software programming control method by large scale integrated circuit. The sampling circuit can handle the data at the highest sampling rate of 3GHz. The systems have the quality of high integration, low power consumption, simple structure and excellent performance. All the programs have been proven feasible and achieving good results.
