| Abstract: | By means of the theory of transmission current-switches, this paper analyzes the theory of multivalued A/D converter, and has designed the circuit of current-mode CMOS for multivalued ADC which based on control threshold technology. Computer simulation shows that it has a correct logic function. By virtue of this design method, the complicated circuits for analog signal processing can be omitted, the circuit structure of CMOS A/D converter is greatly simplified, and the information density for A/D converter has been improved. |
