New MEMS Oscillators Boast Long-term Stability

Leave a Comment / Tech News Updates / By

AUSTIN, Texas–(BUSINESS WIRE)–Silicon Labs (NASDAQ: SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, today introduced the industry’s most highly integrated MEMS-based oscillators designed to replace general-purpose crystal oscillators (XOs) in cost-sensitive, low-power and high-volume industrial, embedded and consumer electronics applications such as digital cameras, storage and memory, ATM machines, point-of-sale equipment and multi-function printers. The …

Graphene MEMS Outperforms Silicon

Leave a Comment / Tech News Updates / By

Graphene can increase the sensitivity of micro-electro-mechanical system (MEMS) Sensors by up to 100 times, according to researchers at the Swedish KTH (Kungliga Tekniska Högskolan) Royal Institute of Technology in Stockholm. “The advantage of using graphene membranes for piezoresistve Sensors is their extreme thinness,” Frank Niklaus, a professor at KTH, told EE Times. “The sensitivity …

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

Leave a Comment / Tech News Updates / By

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 …

Reverse engineering the silicon in the ARM1 processor

Leave a Comment / Tech News Updates / By

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 …
