Ambipolar double-gate FET binary-decision- diagram (Am-BDD) for reconfigurable logic cells

A novel Ambipolar Binary Decision Diagram (Am-BDD) is proposed in this paper, to adapt this logic synthesis and verification technique to logic built with ambipolar devices. We demonstrate how this method enables us to build DG-CNTFET-based n-input reconfigurable cells based on pass-transistor-logic obtained from Am-BDDs. We also show how specific correlations between configuration signals can lead to a minimization of their total number. Using the Am-BDD technique, we designed a reconfigurable 2-input cell capable of achieving 16 functions and demonstrating a significant reduction in power consumption (6x) with a reduced worst-case time delay when compared to a manually designed reconfigurable 2-input dynamic logic cell DRLC-7T.
