A CMOS quaternary-to-binary logic decoder

This paper proposes a quaternary-to-binary logic decoder using current-mode multiple-valued logic (MVL) CMOS circuits. The circuit is achieved a device reduction of 23.5%, an interconnection reduction of 25.0%, and a power-delay-product reduction of 43.1%. Therefore, this circuit is superior to the previous circuit in both the circuit occupied area and the reliability. The validity and effectiveness of the proposed circuits are verified through the HSPICE under Hynix 0.25 um standard CMOS technology with the supply voltage 2.5 V.
