Monostable Multivibrator using Transistors

Multivibrator is a non linear oscillator or function generator which can generate square, rectangular and pulse waves. Monostable Multivibrator or One-Shot Multivibrator has only one stable state. By default monostable multivibrator will be in its stable state, but when triggered it will switch to unstable state (quasi-stable state) for a time period determined by the RC time constant in the circuit. Monostable Multivibrator using Transistors - Circuit Diagram In the above circuit diagram we can find two transistors which are wired as switches. Please read [...]

Nano Vacuum Tubes : The Future of Computing

Vacuum Tubes Reloads.... Vacuum Tubes are used in computing, switching, amplification and rectification right up to 60s. Then it died a quick death since most applications solid state device such as semiconductor devices have replaced them. We all know that Semiconductor devices are small in size and cheaper than vacuum tube devices. Silicon transistors are cheaper but they are slower and susceptible to radiation. The performance of Silicon Transistors, far away from Vacuum Tube devices due to their compact size, no heating time, reduced [...]

Intel launched Ivy Bridge Chips with 3D Transistors and 22nm Process

The giant chip maker Intel has finally released its 3ed generation chips named Ivy Bridge. They says that the new microprocessor chips used fundamentally different technology. These chips comes with 3D Transistors and are manufactured at 22nm process. The new technology will ensure high processing speed along with power saving. The chip makers keep the pace of Moore's law by making the new chips using 3d transistor technology along with other advanced capabilities. We can hope that, customers will certainly welcome the [...]

Optical Transistors Out of Silicon : Significant step towards Optical Computing

We all know that electrons are good at processing information, but they are incapable of carrying information over long distances. On the other hand, Photons can carry information all around the planet but their processing is hectic. So we use electrons for processing and photons for long distance data transmission. Thus we need significant amount of power to convert optical information to electronic and vice versa. Hence there is no wonder in the fact  that  researchers pay significant interest in developing [...]

Biodegradable Transistors made from Human Body !!!

A team of researchers including Ph.D. students Elad Mentovich and Netta Hendler of TAU’s Department of Chemistry and The Center for Nanoscience and Nanotechnology, with supervisor Dr. Shachar Richter and in collaboration with Prof. Michael Gozin and his Ph.D. student Bogdan Belgorodsky had developed a new generation of  nano-sized technology that are both flexible and biodegradable to replace silicon in the field of semiconductor electronics. Researchers have integrated cutting edge techniques from different fields of science to create protein based [...]

More Energy Efficient Transistors through Quantum Tunneling

Researchers at the University of Notre Dame and Pennsylvania State University had announced that they had developed Tunneling Field Effect Transistor (TFET), which takes the advantage of a peculiar behaviour of electrons at quantum level. We know that transistors are the basic building block of electronic devices that power this digital world. The growth of computing power over the last 40 years had made possible by increasing the number of transistors that integrated in single silicon chip. Now we have more [...]

Graphene Transistors to Replace Silicon

Researchers at Manchester University makes a new footprint in the field of transistors. They developed a technique for improving the ON-OFF ratio of  Graphene transistors.  The newly developed Graphene transistors might replace silicon in computer chips. The main benefit of using Graphene for making transistors is that, we can scale down size of transistors to 10-15 atom across. Thus transistors can be made of nano-scale, thus it can have more transistors in chips, and makes them more powerful. Graphene's low resistance to the flow of electrons [...]

Germanium Nanowire Transistors

Intel revels that they had developed P-Channel Germanium Transistors,it is combined with complementary III-V N-channel transistors and forms  CMOS architecture. Germanium was found to be limited due to greater current leakage, for many years. Now the focus on germanium is due to the fact that, Germanium is more mobile than Silicon. For more than a decade, the extensive use of Germanium over Silicon has been discussing, and the first Germanium processors were predicted before 15 years, to arrive in 2007 to 2008 time. Similarly the [...]
