متن کاملDesign and Implementation of Low Power 8-bit Carry-look Ahead Adder Using Static CMOS Logic and Adiabatic Logic
Addition forms the basic structure for many processing operations like counting, multiplication, filtering etc. Adder circuits that add two binary numbers are of great interest for many designers. The simplest approach to design an adder is to implement gates to yield the required logic function. Carry-look ahead adder is a major functional block in arithmetic logic unit due to its high speed o...

متن کاملDesign of Carry Skip Adder Using Han Carlson Adder for Low Power and High Speed VLSI Applications
Adders are the basic building block in the arithmetic circuits. In order to achieve high speed and low power consumption a 32bit carry skip adder is proposed. In the conventional technique, a hybrid variable latency extension is used with a method called as parallel prefix network (Brent-Kung). As a result, larger delay along with higher power consumption is obtained, which is the main drawback...
