The Tiniest 1nm Gate Transistor
https://www.electronics-lab.com/tiniest-1-nm-gate-transistor/
A research team led by faculty scientist Ali Javey at Berkeley Lab have debuted the smallest transistor ever reported. A gate structure of just 1 nm long can bring Moore’s law back again after the demonstration of the recent Silicon (Si) transistor with 5 nm gate. It was predicted that transistors will fail below 5 […]
Use a transistor as a heating element
https://www.electronics-lab.com/use-a-transistor-as-a-heating-element/
REC Johnson, B Lora Narayana, and Devender Sundi share their design idea on how to use a transistor as a heating element. It is common to use transistors for driving resistive heating elements. However, you can use the heat that a power transistor dissipates to advantage in several situations, eliminating the need for a separate […]
Simple two-transistor circuit lights LEDs
https://www.electronics-lab.com/simple-two-transistor-circuit-lights-leds/
Barry Tigner @ edn.com has a design idea on how to power a LED from a 1.5V battery using two easily available transistors. A previous Design Idea describes a circuit that uses an astable multivibrator to drive an LED (Reference 1). The circuit in Figure 1 uses a simpler alternative approach. The circuit uses a […]
What Will Happen to Moore’s Law in 2021?
https://www.electronics-lab.com/will-happen-moores-law-2021/
Moore’s law states that the number of transistors doubles every two years. Rachel Courtland from IEEE Spectrum explained the sharp turn of Moore’s law in 2021. Chip manufactures will switch to another way of boosting the density in the chip by having multilayer chips using vertical geometry, and we’ve already seen the 3D concept in […]
Berkeley Lab makes graphene-MoS2 transistor
https://www.electronics-lab.com/berkeley-lab-makes-graphene-mos2-transistor/
U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a way to assemble transistors based on the 2D materials graphene and molybdenum disulfide. By Peter Clarke @ edn-europe.com The method etches narrow channels in conducting graphene laid down on a silicon-dioxide substrate. These channels are then filled with a transition-metal dichalcogenide, or […]
Simple crystal tester
https://www.electronics-lab.com/simple-crystal-tester-3/
Dilshan Jayakody build a simple crystal tester based on Colpitts oscillator. He writes: This is simple Colpitts oscillator to test commonly available passive crystals which range between 2MHz to 27MHz. This unit must connect to an oscilloscope and/or frequency counter to get the frequency of the crystal. This circuit is design to work around 9V […]
USB curve tracer for NPN transistors
https://www.electronics-lab.com/usb-curve-tracer-npn-transistors/
Dilshan Jayakody documented his USB port base NPN transistor curve tracer project: Curve tracer is an electronic test instrument to analyze the characteristics of transistors and other discrete semiconductors. In this post we construct USB base curve tracer to analyze properties of NPN transistors. This curve tracer is build around Microchip’s PIC18F4550 MCU and it […]
Record-setting flexible phototransistor revealed
https://www.electronics-lab.com/record-setting-flexible-phototransistor-revealed/
Researchers at the University of Wisconsin-Madison have revealed a unique phototransistor that is flexible and faster and more responsive than any similar phototransistor. The innovative phototransistor could improve the performance of myriad products — ranging from digital cameras, night-vision goggles and smoke detectors to surveillance systems and satellites — that rely on electronic light sensors. Integrated […]
