BROADCOMS SINGLE SILICON PHOTO MULTIPLIER IS BEST SUITED FOR THE DETECTION OF LOW LEVEL PULSED LIGHT SOURCES

BROADCOM’S SINGLE-SILICON PHOTO-MULTIPLIER IS BEST SUITED FOR THE DETECTION OF LOW-LEVEL PULSED LIGHT SOURCES

Leave a Comment / Electronics News Updates /

The Broadcom® AFBR-S4N33C013 is a single-silicon photo-multiplier (SiPM) used for ultra-sensitive precision measurement of single photons. The active area is 3.0 mm × 3.0 mm. A high packing density of single chips is achieved using through-silicon-via (TSV) technology and a chip-sized package (CSP). Larger areas can be covered by tiling multiple AFBR-S4N33C013 CSPs almost without any edge losses. The

NANO SANDWICHES IN ELECTRONICS SIGNIFICANTLY REDUCE RISK OF OVERHEATING

NANO-SANDWICHES IN ELECTRONICS SIGNIFICANTLY REDUCE RISK OF OVERHEATING

Leave a Comment / Electronics News Updates /

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

New Ultrathin Semiconductors Can Make More Efficient and Ten Times Smaller Transistors Than Silicon

Leave a Comment / Electronics News Updates /

The researchers at Stanford University have discovered two ultrathin semiconductors – hafnium diselenide and zirconium diselenide. They share or even exceed some of the very important characteristics of silicon. Silicon has a great property of forming “rust” or silicon dioxide (SiO2) by reacting with oxygen. As the SiO2 acts as an insulator, chip manufacturers implement this property

Reverse engineering the silicon in the ARM1 processor

Leave a Comment / Electronics News Updates /

How can you count bits in hardware? In this article, I reverse-engineer the circuit used by the ARM1 processor to count the number of set bits in a 16-bit field, showing how individual transistors form multiplexers, which are combined into adders, and finally form the bit counter. The ARM1 is the ancestor of the processor
