Researchers Developed a Very Powerful Mini Synchrotron That Can Fit On A Tabletop
https://www.electronics-lab.com/researchers-develop-powerful-mini-synchrotron-can-fit-tabletop/
A synchrotron is a particular type of cyclic particle accelerator which is used to accelerate quantum level charged particles at a very high velocity, traveling around a fixed closed-loop path. It is one of the first accelerator concepts to enable the construction of large-scale facilities because they are very efficient in beam focusing, bending, and […]
Op amps, comparators – smaller than ever
https://www.electronics-lab.com/op-amps-comparators-smaller-ever/
Aimee Kalnoskas @ eeworldonline.com discuss about TI’s tiny OPAMP and comparators. Texas Instruments introduced the industry’s smallest operational amplifier and low-power comparators at 0.64 mm2. As the first amplifiers in the compact X2SON package, the TLV9061 op amp and TLV7011 family of comparators enable engineers to reduce their system size and cost, while maintaining high […]
