Adders are surveyed based on their delay, power and area. Most of the research in the last few years have concentrated on reducing the delay of adders and also power consumption. Carry skip adders are widely used in tree structure configuration for high speed performance. This paper analysis on speed, delay, area and temperature effect of 256 bit carry skip adder using 22nm strained silicon CMOS technology and it uses a supply voltage 0.8V. The simulation results are obtained by a HSPICE software tool. This dynamic carry skip adders consumes only 50% area compared to static CMOS technology based carry skip adders and also speed of the circuit will be increased.
