SEMICONDUCTORS ELTE 1403 Forward biased diode: cathode anode Varactor is a silicon diode optimized for its variable capacitance when reversedbiased. Used for tuning frequencydependent equipment. Zener Diode is designed to operate in the breakdown region; used for voltage regulation. Varactor Zener N + P electron flow depletion layer An ideal diode acts like a closed switch when forward biased and an open switch when reverse biased. 1st approximation calculations assume

The reproductive system is a collection of internal and external organs (male and female) that work together for the purpose of recreating. Many scientists argue that the reproductive system is the most important system in the body. Without the reproductive system we would not be able to reproduce. 1 For the male reproductive system there are two major parts: testes‚ where the sperm is produced and the penis. In males the penis and urethra belong to both the urinary system and reproductive system

Multiple frequency’ (DTMF) tone. The robot receives these tones via the receiver mobile phone which is on board. The received tone is processed by the microcontroller with the help of DTMF decoder IC CM8870DE . This IC communicates with the motor driver IC l293d through the microcontroller interface which drives the motor in forward‚ reverse‚ right and left directions according to the user’s key press. The microcontroller featuring in this project will be the AVR microcontroller

as little as a few years’ time more and more transistors are squeezed in a single silicon chip having the capabilities of doing tremendous amounts of number crunching equations and such. He also points out the different factors that will affect the IC such as its reliability‚ costs‚ dimensions‚ yields‚ heating problems and linear circuitry. Furthermore‚ since Moore’s time the technological advances have just begun as to our present technological innovations are starting to incline with much progressiveness

In electronics‚ an integrated circuit (also known as IC‚ microcircuit‚ microchip‚ silicon chip‚ or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices‚ as well as passive components) that has been manufactured in the surface of a thin substrate of semiconductor material. Integrated circuits are used in almost all electronic equipment in use today and have revolutionized the world of electronics. A hybrid integrated circuit is a miniaturized electronic circuit constructed
