linear integrated circuits by d choudhury roy pdf free

A linear integrated circuit (linear IC) is a solid-state analog device characterized by a theoretically infinite number of possible operating states. It operates over a continuous range of input levels. In contrast, a digital IC has a finite number of discrete input and output states.

Within a certain input range, the amplification curve of a linear IC is a straight line; the input and output voltages are directly proportional. The best known, and most common, linear IC is the operational ....etc

This RFID based HOME SECURITY project is developed to build a security system for a Home / office to prevent others from entering the important piece / room controlling the RFID selecting a suitable RFID card. The RFID tag gives the identifier unique whenever he reads the card information. Identifying this information is sent to the microcontroller to check the good card to take a measure of security. If the ID card is the original information, it allows to enter the room, if not give the buzzer as an indication of bad person tried to enter the ....etc

The voltage and current at specified points in the circuits of analog chips vary continuously in time. In contrast, digital chips only use and create voltages or currents at discrete levels, with no intermediate values. In addition to Transistors, analog chips often have a larger number of passive elements (Inductor/Capacitors/Resistors) than digital chips typically do. Inductors tend to be avoided because of their large size, and a transistor and capacitor together can do the work of an inductor. (When this method is used in a CFL, you get an ....etc

RFID tags store much more information than bar codes, though high costs so far have limited their growth.But now it may be possible to cut costs drastically by printing RFID antenna circuitry directly on a corrugated shipping box,printed antennae with lines spaced just 0.003 in. apart. Tests show the antennas are sufficiently conductive to work in a commercial environment. PRPflexo's ExSpect flexo plates in other applications print clear and legible two-point type on rough corrugated board and Tyvek, says the company. ....etc

What is electronics?

The word electronics is derived from electron mechanics, which means to study the behavior of an electron under different conditions of applied electric field.

The branch of engineering in which the flow and control of electrons in vacuum or semiconductor are studied is called electronics. Electronics can also be defined as the branch of engineering in which the electronic devices and their utilization are studied.

The motion of electrons through a conductor gives us electric current. This electric current can be ....etc
