What is a Quantum Interference Transistor?
918570
A semiconductor device using interference effects of electron waves passing through a multichannel, wherein the multichannel is formed by a Dirac-delta-doped layer. A method of manufacturing a semiconductor device comprising the steps of: selectively forming a region of a predetermined crystallographic orientation onto a semiconductor substrate; and alternately growing the first semiconductor layer and the second semiconductor layer whose electron affinity is smaller than that of the first semiconductor layer onto the region of the predetermined crystallographic orientation by a vapor-phase growth method so as to have a convex shape in a manner such that an area of an upper layer is smaller. A semiconductor device in which a channel portion comprising a zigzag fine line is provided between a source and a drain.

The Q-factor is the quality factor of an amplifier.  The exact mathematical definition may vary depending on what type of amp it is.  Basically, it means how well it passes what it is supposed to pass, and how well it rejects what it is supposed to reject.\n\nThe SR flip-flop is a bistable device that can exist in an on state or an off state.  The two inputs cause it to set or reset.

Tunneling Theory \n  \nThe simplest model of quantum transport in devices is to describe the problem in terms of the scattering of the electron wavefunction by a spatially varying potential. One assumes that this potential is situated between two electron reservoirs, each of which emits particles with an equilibrium distribution into the scattering region. The reservoirs will, in general, have different chemical potentials, their difference representing an applied bias voltage. The net flux of electrons passing between the reservoirs constitutes the electrical current conducted by the device. A single-particle Schrödinger equation can only describe a situation in which the electrons move perfectly coherently throughout the device. Any loss of coherence due to inelastic collisions requires a higher-level description. Nevertheless, the solutions of Schrödinger 's equation remain one of the fundamental tools available to understand and predict the behavior of quantum-scale devices.

Need to have common mode noise rejection on the front end. \n\nLeads should have a ferrite bead or torus around a cable to prevent radio frequency interference from being transmitted down the wire.\n\nAliasing:\nTo avoid aliasing, the input to an ADC must be low-pass filtered to remove frequencies above half the sampling rate. This filter is called an anti-aliasing filter, and is essential for a practical ADC system.\n\nDither:\nIn A to D converters, performance can be improved using dither. This is a very small amount of random noise (white noise) which is added to the input before conversion. Its amplitude is set to be about half of the least significant bit. Its effect is to cause the state of the LSB to randomly oscillate between 0 and 1 in the presence of very low levels of input, rather than sticking at a fixed value. Rather than the signal simply getting cut off altogether at this low level (which is only being quantized to a resolution of 1 bit), it extends the effective range of signals that the A to D converter can convert, at the expense of a slight increase in noise - effectively the quantization error is diffused across a series of noise values which is far less objectionable than a hard cutoff. The result is an accurate representation of the signal over time. A suitable filter at the output of the system can thus recover this small signal variation.\n\nSampling Rate:\nSince a practical ADC cannot make an instantaneous conversion, the input value must necessarily be held constant during the time that the converter performs a conversion (called the conversion time). An input circuit called a sample and hold performs this task—in most cases by using a capacitor to store the analogue voltage at the input, and using an electronic switch or gate to disconnect the capacitor from the input.

well. it looks tiny to all of us, but infact it has millions of transistors arranged in particular circuitry within itself doing the job. \n\nthis link will help you in detail\nhttp://computer.howstuffworks.com/microprocessor.htm

infact the circuitry is so designed that the total power consumption is very small and thats the reason behind making such ICs using the nano technology. these days an IC may comprise millions of transistors allowing u to make the designs smaller and smaller. along with low cost

Currently not possible. Scillicon is not the most efficient but its abundance on earth is amazingly practicle. They've found ways to use nickle for example that can be 1000 times faster, but they'd have to reconstruct all the mechanism of the computer. \n\nnewscientist.com search quantum computer\n\nhttp://www.google.com/search?q=site:newscientist.com+quantum+computer

Wow, I can't believe you have been waiting so long for an answer.\n\nThere are a couple of papers you can review:\n\ne.g. http://www.nsti.org/publ/MSM2002/348.pdf#search='frequency%20mosfet%20parameter'\n\nand here also:\nhttp://www.freewebs.com/anishamukherjee/Papers.htm\n\nThere is a tool here, but you need to pay, and I have not used it myself:\n\nhttp://www.highbeam.com/library/doc0.asp?docid=1G1:79591050&refid=ink_tptd_mag_test1&skeyword=&teaser=

Something that adds numbers using digital logic. It's works by connecting the carrys from four full adders to create a 4 bit ripple adder. The carry ripples down the adders, which is why it's called a ripple adder.\n\nGenerally considered a slow design. Look into Carry Look Ahead adders if you want something faster.

My vote would be for 'light-based' semiconductors (although semiconductor isn't the right word)\n\nThe technical ability to replicate the integrated circuit, such as those used in computers, with devices using light instead of electricity.\n\nBenefits would include lower operational cost, (resistance in electrical circuits wastes energy by creating unwanted heat) and faster switching times due to lack of radio frequency interference being generated that affects nearby circuitry.\n\nJust my $0.02\n\nOuzinki

Logic circuits built out of transistors. Those transistors are today built into an IC chip. The most important circuits for the calculator are the 'full adder' circuit, and various memory circuits.

A transistor is a semiconductor device that uses a small amount of voltage or electrical current to control a larger change in voltage or current. Because of its fast response and accuracy, it may be used in a wide variety of applications, including amplification, switching, voltage stabilization, signal modulation, and as an oscillator. The transistor is the fundamental building block of both digital and analog circuits — the circuitry that governs the operation of computers, cellular phones, and all other modern electronics. Transistors may be packaged individually or as part of an integrated circuit chip, which may hold thousands of transistors in a very small area.
