Abstract

The ternary-binary conversion is reached by two CMOS inverters dimensioned extremely unsymmetrically with regard to their W/L ratio and connected in parallel at their inputs. By further addition of a NAND or a NOR gate the circuit can be used in an integrated circuit as option releasing stage without additional terminal for the option signal which has only to be chosen as the middle value of the ternary signal whereas its lower and upper values are the binary signals.
