The advancement in semiconductor has made the world of wireless possible and moreover it has made the wireless embedded systems to shrink day by day. Due to advancement in VLSI chip design, the theories of past are becoming realties. Be a design of complex compression algorithms or a mixed signal component design, VLSI designs makes it possible. The demand for real-time VLSI compression for high-speed wireless local area networks is rising. VLSI Engineers are today very much part of the wireless embedded systems. Complex wireless embedded component are able to function only when they are developed in hardware, the software fails to meet the requirements drastically. Using the Advance VLSI design and Mixed signal design the VLSI, designing complex functions are feasible.
