| Abstract: | Based on the theory of transmission current-switches, the principle of A/D converter is analyzed. The design of current-mode CMOS A/D converter is implemented. Compared with the conventional A/D converter design method, the complicated circuits for analog signal processing can be omitted, and the circuit structure of CMOS A/D converter is greatly simplified. Experiment result shows that the logical function of the circuit designed by this method is correct. |
