The RGATE: An 8-in-1 Polymorphic Logic Gate Built From Reconfigurable Field Effect Transistors

Abstract

We present the hardware implementation of a reconfigurable universal logic gate, that we call RGATE, able to deliver up to eight different logic functionalities and based on a symmetric four-transistors cell. The polymorphic logic gate is realized with three-gated Reconfigurable Field Effect Transistors. Fabrication and electrical characteristics of the elements are discussed. To validate the presented concept, we show an experimental demonstration of NOT, NAND, NOR, XOR and XNOR Boolean functions as well as multiplexing capabilities measured by dynamically reconfiguring the same RGATE.

Directed Acyclic Graph-Based Datapath Synthesis Using Graph Isomorphism and Gate Reconfiguration

“…Reconfigurable logic gates represent a class of emerging devices capable of implementing multiple logic operators within a single cell [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Drawing inspiration from various physical mechanisms, they have the potential to enhance the area efficiency of logic circuits by enabling a greater number of functions to be performed using a fixed number of cells.…”
