Common Emitter BJT Amplifier Design Current Mirror Design


Some Random Observations
● Conditions for stabilized voltage source biasing
● Emitter resistance, RE, is needed.
● Base voltage source will have finite resistance, RB.
● needs to be much larger than RB.
● Small RB - relative to RS - will attenuate input signal.
● Larger RE permits larger RB, but results in lower gain.
● Gain = -RC/RE for RE >> re.
● Split RE with bypassing increa ....etc

Surface conduction Electron emitter Display


The SED technology has been developing since 1987. The flat panel display technology that employs surface conduction electron emitters for every individual display pixel can be referred to as the Surface-conduction Electron-emitter Display (SED). Though the technology differs, the basic theory that the emitted electrons can excite a phosphor coating on the display panel seems to be the bottom line for both the SED display technology and the traditional ....etc

Surveillance, Espionage or spying involves individual obtaining information that is considered secret or confidential without the permission of the holder of the information. Spying area in military ground where enemy stay can be took before taking any action.
A robot is a virtual or mechanical artificial agent. In practice, it is usually an electro mechanical system which, by its appearance or movements, conveys a sense that it has intent or agency of its own.
Our aim in building this projec ....etc

ABSTRACT
BiCMOS technology is a combination of Bipolar and CMOS technology. CMOS technology offers less power dissipation, smaller noise margins, and higher packing density. Bipolar technology, on the other hand, ensures high switching and I/O speed and good noise performance. It follows that BiCMOS technology accomplishes both - improved speed over CMOS and lower power dissipation than bipolar technology. The main drawback of BiCMOS technology is the higher costs due to the added process complexity. Impurity profiles have ....etc

1. INTRODUCTION
The history of semiconductor devices starts in 1930â„¢s when Lienfed and Heil first proposed the mosfet. However it took 30 years before this idea was applied to functioning devices to be used in practical applications, and up to the late 1980 this trend took a turn when MOS technology caught up and there was a cross over between bipolar and MOS share.CMOS was finding more wide spread use due to its low power dissipation, high packing density and simple design, such that by 1990 CMOS ....etc

ABSTRACT
With a 100-year head start over more modern screen technologies, the CRT is still a formidable technology. Itâ„¢s based on universally understood principles and employs commonly available materials. The result is cheap-to-make monitors capable of excellent performance, producing stable images in true colour at high display resolutions. But in the world of miniaturization, Cathode ray tubes (CRT) are giant dinosaurs waiting for extinction. A CRT uses a single-point hot electron source that is scanned across the sc ....etc

Autonomous Stabilization System for a Coaxial Helicopter
ABSTRACT
The purpose of this project was the design of a fully autonomous stabilization system intended for systems capable of intelligent programming and navigation. This means that the design focuses mainly on the control feedback systems that control the helicopterâ„¢s motors that then provide lift to increase and decrease altitude, and produce a tilt about the helicopterâ„¢s central vertical axis which would be used for stabilization and potentially later ....etc

ABSTRACT
Hypersonic sound technology from American Technology Corporation employs ultrasonic waves to create audible sound in the air. It works by using harmless ultrasonic tones that we can't hear. These tones use the property of air to create new tones that are within the range of human hearing. The result is audible sound. The acoustical sound wave is created directly in the air molecules by down-converting ultrasonic energy to the frequency spectrum we can hear. Hyper Sonic Sound is produced without the excess bag ....etc

A Surface-conduction Electron-emitter Display (SED) is a flat panel display technology that uses surface conduction electron emitters for every individual display pixel. The surface conduction electron emitter emits electrons, that excite a phosphor coating on the display panel which is similar to the basic concept found in traditional cathode ray tube (CRT) televisions. This means that SEDs can combine the slim form factor of LCDs with the high contrast ratios and can also refresh rates making the picture quality of CRTs better .The researches ....etc
