In this paper,the wideband analog signal sampling is realized by using an integrated ADC component on the radio frequency field programmable gate array(RF-FPGA)chip.The use of the ADC-on-chip is described from two aspects:hardware peripheral circuit design and software interface data format.In addition,the sampling results of the first and second Nyquist intervals are detailed.Finally,MATLAB is used for off-line analysis of the sampling results in terms of three metrics,namely signal-to-noise ratio,spurious-free dynamic range,and effective number of bits.
