Design of Dynamic Digital Circuits with n-Channel Multiple-Input Floating-Gate Transistors

Abstract

Dynamic circuits using n-channel multiple-input floating-gate MOS(FGMOS) transistors to realize binary and ternary logic are presented. In binary domino circuits, the n-channel FGMOS transistors are used to replace the nMOS logic block to simplify the circuit structure. By using the advantage that voltage signals are easy to be added by means of floating gate in multiple-input FGMOS transistor, a summation signal is introduced in binary circuit design. Finally, two dynamic ternary literal circuits are designed using n-channel FGMOS transistors. The proposed voltage-mode dynamic ternary literal circuits have simpler structure. All the proposed dynamic circuits are verified by HSPICE simulation results with TSMC 0.35amu;m 2-ploy 4-metal CMOS technology.
