Because this is not a limitation from basic physical laws, novel architectures for MOSFETs will be needed to improve again the electrical characteristics and thus pave the way to much smaller transistors than expected in the past. 25nm CMOS seems to be feasible using very thin silicon substrates...
A small current can turn a larger current on and off. A silicon chip is a piece of silicon that can hold thousands of transistors. With transistors acting as switches, you can create Boolean gates, and with Boolean gates you can create microprocessor chips. The natural progression from ...
The optical storage device that most of us are familiar with is thecompact disc(CD). A CD can store huge amounts of digital information (783 MB) on a very small surface that is incredibly inexpensive to manufacture. The design that makes this possible is a simple one: The CD surface is...

PCs go small—and smaller According to Moore’s Law, the number of transistors in a dense integrated circuit has doubled around every two years. With this consistent increase in the processing power available in the same physical space, the size of processors has continually decreased—and the ...
The voltage-control viewpoint shown by the Ebers-Moll explanation does appear widely in textbooks, but it certainly isn't widely learned. If it had been learned, then people wouldn't get angry when they hear that transistors are voltage-controlled; that the collector current is proportional to...
A common question I get is why do we need the transistor? Why not connect the LED and resistor directly to the battery? The advantage of a transistor is that you can use a small current or voltage to control a much larger current and voltage. ...
The next year, Bell Labs announced to the world that it had invented working transistors. The original patent name for the first transistor went by this description: Semiconductor amplifier; three-electrode circuit element utilizing semi conductive materials. It was an innocuous-sounding phrase. But ...
an electrical circuit built around aninverting operational amplifier. The inverting amplifier is a complex semiconductor device, made up of a number of transistors, resistors and capacitors. The details of its operation would fill an entire article by itself, but here we can get a general sense ...
transistors can amplify signals because of their ability to control a larger current with a smaller input current or voltage. in an amplification process, a small input signal applied to the base of a transistor causes a much larger current to flow through the collector, resulting in an ...
