We are fast approaching the day when anyone with an idea will be able to create an application or a website in hours. In the immortal words of Ferris Bueller, “Life moves pretty fast. If you don’t ...

If you’ve been to a wedding or a downtown coffee shop in the last 10 years, you’ve probably seen those little lightboxes that are so popular these days. They consist of letters placed ...

How It Works This project demonstrates a push-pull switching circuit using complementary BJT transistors to alternately drive two LEDs. The circuit uses: 2N2222A (NPN transistor) 2N5401 (PNP ...

Abstract: The unsustainable downscaling of Si transistor run counter to the rapid development of big data. Further geometric sizing needs industrial strategies and promotion. The two-dimensional ...

Abstract: We propose a novel transistor-level synthesis method to minimize the number of transistors needed to implement a digital circuit. In contrast with traditional standard cell design methods or ...
