Main goal of this paper is to propose a compact library of polymorphic gates
based on suitable type of reconfigurable transistors. In fact, their exploitation
brings a significant advantage for space-efficient synthesis of complex
polymorphic circuits. Actual behaviour of those transistors closely depends on so
called ambipolar property. That particular aspect simply allows the selection of
n- or p- channel operating mode of the transistor structures which is controlled
by means of switching the voltage level at a dedicated control electrode.
The gates were developed by an evolution approach using Cartesian genetic
programming. Various discrete switch-level ambipolar transistor models extended
by taking into account the threshold voltage drop degradation effect were used.
A diverse range of polymorphic gates were designed, which clearly shows
significant transistor savings compared to the conventional approaches. Finally,
the individual components that belong to the library also suggest the opportunity
how to considerably reduce the target size of complex polymorphic circuits.
