Ambipolarity, a unique feature typically found in some post-silicon devices, e.g.
CNT or organic FETs, is still treated today just as something rather peculiar.
But in reality, it does not hinder such devices from utilization when it comes to
the implementation of logic. From other point of view, this feature could be
perceived as an opportunity to implement the logic in more refined and efficient
way. The practical impact of ambipolarity results in devices which becomes more
versatile than conventional FET element.
In this paper, a set of multifunctional logic gates based on ambipolar FETs is
presented. The multifunctionality of these gates means that each gate could
exhibit one of two defined functions in a given moment. The selection of their
function depends on circumstances under which the circuit is operated. The
proposed set of gates could be employed in multifunctional circuits using
techniques and procedures established for polymorphic electronics. This field of
study, yet proposed nearly 20 years ago, now offers synthesis methods and
application approaches to obtain an efficient implementation of more than one
function in one logic circuit.
