A new MOS current-mode multiple-valued（MV） logic circuit is proposed in this paper. By taking 10-valued circuits as an example

various 10-valued circuits

required by the complete multiple-valued system

are suggested. The possibility of applying these circuits to realize some practical systems is also studied. Testing of sample chips

fabricated by the standard CMOS technology

shows that this kind of multiple-valued logic circuits not noly has the complete logic functions

but also possesses the advantages of high integration density

simplicity of circuit structure

fesibility and’good reliability

as compared with other types of mu-liple-valued circuits.
