Presenting the Common Base Amplifier In this article, we present the last topology of amplifiers for bipolar transistors known as the Common Base Amplifier (CBA). In Figure 1 below, the electric diagram of a CBA is presented, no particular bias circuit or decoupling capacitors are shown here. Some specifications need to be highlighted for CBAs […]
Common Collector Amplifier

Presenting the Common Collector Amplifier This article deals with another type of bipolar transistor architecture used to amplify signals that is commonly known as Common Collector Amplifier (CCA). The CCA can also sometimes be called emitter-follower amplifier and we will understand why later in this article. The first figure below is a simplified electric diagram […]

Engineers produce smallest 3-D transistor yet
https://www.electronics-lab.com/engineers-produce-smallest-3-d-transistor-yet/
Process that modifies semiconductor material atom by atom could enable higher-performance electronics. Researchers from MIT and the University of Colorado have fabricated a 3-D transistor that’s less than half the size of today’s smallest commercial models. To do so, they developed a novel microfabrication technique that modifies semiconductor material atom by atom. The inspiration behind […]
Building a Transistor Curve Tracer
https://www.electronics-lab.com/building-transistor-curve-tracer/
paulv @ paulvdiyblogs.net designed and build a transistor curve tracer and documents the process on his personal blog. He writes: It’s not that I use a Curve Tracer that much, but if you want to categorize or really measure the parameters of a discrete component, there is really no other tool that can do the […]
Nano-sandwiches in Electronics Significantly Reduce Risk of Overheating
https://www.electronics-lab.com/nano-sandwiches-electronics-reduce-risk-overheating-significantly/
A new study about “Reduction of overheating of 2D materials” published in the Journal of Advanced Materials. The work put behind the study is credited to the researchers at the University of Illinois at Chicago College of Engineering. By joining together two-dimensional materials used in nanoelectronic devices between their three-dimensional silicon bases, they formed an ultrathin layer […]
Two bits per transistor: high-density ROM in Intel’s 8087 floating point chip
https://www.electronics-lab.com/two-bits-per-transistor-high-density-rom-in-intels-8087-floating-point-chip/
Ken Shirriff has a detailed write-up about the multi-level ROM in Intel’s 8087 floating point chip: The 8087 chip provided fast floating point arithmetic for the original IBM PC and became part of the x86 architecture used today. One unusual feature of the 8087 is it contained a multi-level ROM (Read-Only Memory) that stored two […]
Single Atom Transistor With Ultra-low Power Consumption
https://www.electronics-lab.com/single-atom-transistor-with-ultra-low-power-consumption/
Karlsruhe Institute of Technology (KIT) researchers in Germany have developed a single-atom transistor that can reduce the power consumption of electronic systems significantly. The device is being developed by Professor Thomas Schimmel and his team at the Institute of Applied Physics (APH). The single-atom transistor switches electrical current by controlled repositioning of a single atom in a gel electrolyte. The […]
