A Multichannel ADC Module Design Method Based on DSP and FPGA

A design method of multichannel ADC module based on DSP and FPGA is proposed in this paper, it is used to realize multichannel AD simultaneous conversion, which can be used in embedded and miniaturized analog-to-digital conversion. Furthermore, this article discusses a convenient way to improve the consistency of multichannel AD conversion, which is using standard signal source to adjusting the deviations of DC bias consistency, amplitude consistency and phase consistency.
