.INTRODUCTION
GiFi stands for Gigabit Wireless. GiFi is a wireless technology which promises high speed short range
data transfers with speeds of upto 5 Gbps within a radius of 10 meters. The GiFi operates on the
60GHz frequency band. This frequency band is currently mostly unused. The Gifi measures 5mm
square and it is manufactured using existing complementary metal-oxide-semiconductor (CMOS)
technology. The same GiFi system is currently used to print silicon chips. This new wireless
technology is named GiFi . The GiFi Chip developed by the Australian researchers. In theory this
technology would transfers GB’s of our fav high definition movies in seconds. So GiFi can be
considered as a challenger to Bluetooth rather than Wi-Fi and could find applications ranging
from new mobile phones to consumer electronics. GiFi allows a full-length high definition movie to be
transferred between two devices in seconds. to the higher megapixel count on our cameras, the
increased bitrate on our music files, the higher resolution of our video files, and so on. We demand
more than ever, but we also want this content to be transfered in the most expedient manner possible.
802.11g and 802.11n are fine and all, but some people want to push the envelope even further. This
chip is 5mm per side and it can operate at a frequency of 60GHz while wifi chip can operate only at
2.4GHz. This have low power conception of 2 watt comes and comes with 1mm antenna.
.1CMOS
GiFi uses CMOS technology. Complementary metal–oxide–semiconductor (CMOS) is a technology
for constructing integrated circuits. CMOS technology is used
in microprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is
also used for several analog circuits such as image sensors, data converters, and highly
integrated transceivers for many types of communication. Frank Wanlass patented CMOS in 1967 (US
patent 3,356,858).
CMOS is also sometimes referred to as complementary-symmetry metal–oxide–semiconductor (or
COS-MOS). The words "complementary-symmetry" refer to the fact that the typical digital design
style with CMOS uses complementary and symmetrical pairs of p-type and n-type metal oxide
semiconductor field effect transistors (MOSFETs) for logic functions.
CMOS (complementary metal-oxide semiconductor) is the semiconductor technology used in
the transistors that are manufactured into most of today's computer microchips. Semiconductors are
made of silicon and germanium, materials which "sort of" conduct electricity, but not enthusiastically.
Areas of these materials that are "doped" by adding impurities become full-scale conductors of either
extra electrons with a negative charge (N-type transistors) or of positive charge carriers (P-type
transistors). In CMOS technology, both kinds of transistors are used in a complementary way to form a
current gate that forms an effective means of electrical control. CMOS transistors use almost no power
when not needed. As the current direction changes more rapidly, however, the transistors become hot.
This characteristic tends to limit the speed at which microprocessors can operate
Two important characteristics of CMOS devices are high noise immunity and low st
