This experimental (3) transistor class A audio power amplifier delivers 25mW into an 8Ω load, or 50mW into a 4Ω load using only a 1.5V power source. At such low voltages, there are many issues to ...

(Nanowerk News) Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team led by Professor Sungjae Cho in the KAIST Department ...

Sometimes, the need arises fora low-distortion buffer amplifiercapable of handling bipolar signals. Youcan use an op amp or integrated bufferfor these applications, but for more flexibility,a discrete ...

For years, the two-dimensional material, graphene, has shown promise in making electronics smaller and more efficient. Now scientists have designed a graphene-based transistor that works with ...

Amorphous oxide semiconductors like IGZO (indium gallium zinc oxide) offer acceptable carrier mobility with very low leakage.

A University of Surrey discovery that solves a problem that has hampered source-gated transistors (SGT) could bring low-cost, flexible displays that require very little energy one step closer. Image ...

Michael Kanellos is editor at large at CNET News.com, where he covers hardware, research and development, start-ups and the tech industry overseas. As the search for a silicon transistor replacement ...

When it comes to 3D transistors, you've probably heard of FinFET -- the 3D, "Tri-gate" transistors that are taking Intel (and eventually other silicon foundries) to 22nm and beyond-- but now a ...

Analog circuitry is usually a small part of a large SoC, but it does not scale in the same way as digital circuitry under Moore’s Law. The power consumed by analog is becoming an increasing concern, ...

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team developed a thickness-controlled black phosphorous tunnel ...
