Design of control module for ADC based on FPGA

In order to increase the flexibility of control for ADC, a new control method for ADC based on FPGA is proposed in this paper. A state transition diagram can be drawn according to the timing diagram of ADC, Which can be realized in FPGA using Very High-speed Integrated Circuit Hardware Description Language (VHDL). The simulate results show that logic in FPGA is consistent with the requirements. The module based on FPGA can be modified just by modifying software, not the hardware.
