Abstract
A high-speed ADC system based on time-interleaving technology is introduced ,it realized the time-interleaving technology in digital way ,and the system is flexible. Using two ADC chips and other peripheral equip?ments,with FPGA as the logic control and data receive cache the hardware circuit of ADC sampling system is built based on time-interleaving technology. The maximal sample rate of this system is up to 400 Msample/s,and the precision is 12 bit. By means of analyzing the time-interleaved ADC system and its channel mismatch error , Matlab is uesd to analyse the source of the channel mismatch error as well as estimate and calibrate the errors of the collected data.关键词
