The Electronics Industry in India took off around 1965 with an orientation towards space and defence technologies. This was rigidly controlled and initiated by the government. This was followed by developments in consumer electronics mainly with transistor radios‚ Black & White TV‚ Calculators and other audio products. Colour Televisions soon followed. In 1982-a significant year in the history of television in India - the government allowed thousands of colour TV sets to be imported into the country

Amplifier with MOSFET Input/Bipolar Output The CA3140A and CA3140 are integrated circuit operational amplifiers that combine the advantages of high voltage PMOS transistors with high voltage bipolar transistors on a single monolithic chip. The CA3140A and CA3140 BiMOS operational amplifiers feature gate protected MOSFET (PMOS) transistors in the input circuit to provide very high input impedance‚ very low input current‚ and high speed performance. The CA3140A and CA3140 operate at supply voltage from

MOLECULAR ELECTRONICS INTRODUCTION Molecular electronics (sometimes called moletronics) is a branch of applied physics which aims at using molecules as passive (e.g. resistive wires) or active (e.g. transistors) electronic components. The concept of molecular electronics has aroused much excitement both in science fiction and among scientists due to the prospect of size reduction in electronics offered by such minute components. It is an enticing alternative to extend Moore’s Law beyond the

this combination may have one or more of the following characteristics: higher input-output isolation‚ higher input impedance‚ high output impedance‚ higher gain or higher bandwidth. In modern circuits‚ the cascode is often constructed from two transistors (BJTs or FETs)‚ with one operating as a common emitter or common source and the other as a common base or common gate. The cascode improves input-output isolation (or reverse transmission) as there is no direct coupling from the output to input

INTRODUCTION Electronics without silicon is unbelievable‚ but it will come true with the evolution of Diamond or Carbon chip. Now a day we are using silicon for the manufacturing of Electronic Chip’s. It has many disadvantages when it is used in power electronic applications‚ such as bulk in size‚ slow operating speed etc. Carbon‚ Silicon and Germanium are belonging to the same group in the periodic table. They have four valance electrons in their outer shell. Pure Silicon and Germanium are semiconductors

He also discusses how the rate in which the number of transistors that could be put onto an integrated circuit will increase. His observations were based on observed data between 1959 and 1964. The rate was doubling every one to two years. He extrapolated these findings and stated that this trend would continue
