  Full adders are important components in applications such as digital signal
processors (DSP) architectures and microprocessors. Apart from the basic
addition adders also used in performing useful operations such as subtraction,
multiplication, division, address calculation, etc. In most of these systems
the adder lies in the critical path that determines the overall performance of
the system. In this paper conventional complementary metal oxide semiconductor
(CMOS) and adiabatic adder circuits are analyzed in terms of power and
transistor count using 0.18UM technology.
