Design of CMOS Full Adder Application Specific Integrated Circuit

Application specific full custom design integrated circuit is a methodology for making a logic cell, circuit or layout specification. Full custom design circuit is the part of Application specific integrated circuit. A gate array or uncommitted logic array as an approach to the design and manufacture of application specific integrated circuit. It requires custom chip fabrication using a complete set of unique masks which define the semiconductor processing of the design. A full custom IC includes some logic cells that are customised using microprocessor full custom IC. In most recent CMOS feature sizes (e.g., 90 nm and 45 nm); leakage power dissipation has become an overriding concern for VLSI circuit designers. A goal of this paper is to evaluate the performance of one-bit Hybrid full adder cell, provide the technical community with a basic understanding of the technologies and options available in the Integrated Circuits (ICs) that they design and use. Hybrid-CMOS design styles utilize various CMOS logic style circuit to build new Full Adder with desired performance.
