  Power loss in the electronic system is a very crucial limiting factor that
can be reduced or minimized with the help of using the reversible logics "a
concept came from Thermodynamics". In this paper the authors shows the concept
of reversible logics for the Electronics system. The logical and physical
designing approach is given in the paper in detail. The contradiction of
logical and physical reversibility with the conventional CMOS designing is also
shows and the solution of that contradiction is also proposed by the authors
using adiabatic logic. This Paper gives a complete and clear idea if the
thermodynamical concept for the electronics industries for power reduction.
