of protection. Transistors A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power‚ a transistor can amplify a signal

chapter 1 intaoduction “Driving to save lives‚ time‚ and money in spite of the conditions around you and the actions of others.”- This is the slogan for Defensive Driving. Vehicle accidents are most common if the driving is inadequate. These happen on most factors if the driver is drowsy or if he is alcoholic. Driver drowsiness is recognized as an important factor in the vehicle accidents. It was demonstrated that driving performance deteriorates with increased drowsiness with resulting crashes

IEEE 2006 Custom Intergrated Circuits Conference (CICC) X/Ku Band CMOS LNA Design Techniques Bagher Afshar‚ Ali M. Niknejad Berkeley Wireless Research Center‚ Dept. of EECS‚ UC Berkeley‚ Berkeley‚ CA 94704‚ USA Abstract— This paper reports two 11 GHz low-noise amplifiers (LNA) in 0.18µm CMOS technology. A cascade two stage LNA achieves 12 dB of power gain‚ 3.5 dB of noise figure‚ and an input/output match of −15 dB/−27 dB at 11GHz‚ while consuming 28mA from 1.8V supply. The second LNA is a modified

by G.E. ’s Frank W. "Bill" Gutzwiller (1). There are various types of thyristors; the type primarily depends on the number of layers and the particular connections to the layers. The word thyristor is a combination of the words “thyratron” and “transistor” (7). The word thyratron was originally a trademark registered by The General Electric Company (G.E.) and invented by G.E. scientist Albert W. Hull in 1929. The word‚ Thyratron is a combination of the Greek prefix thyr- and suffix -tron. The prefix

Source Amplifier The most commonly used topology for LNA design today is the cascode amplifier with inductive source degeneration shown in the Fig. 1. This type of cascode amplifier is called the telescopic cascode amplifier since the cascode transistor is the same type as the input

Definition of ’Moore’s Law’ An observation made by Intel co-founder Gordon Moore in 1965. He noticed that the number of transistors per square inch on integrated circuits had doubled every year since their invention. Moore’s law predicts that this trend[->0] will continue into the foreseeable future. Although the pace has slowed‚ the number of transistors per square inch has since doubled approximately every 18 months. This is used as the current definition of Moore’s law. History The term
