Before transistors and microchips, engineers had limited options for building computing machines. Light bulbs, known as vacuum tubes, were the only components fast and reliable enough to perform ...

If you've never heard of a 'DAC' before, you might be surprised to hear that you most likely use one everyday. DAC stands for digital-to-analogue converter and any device that delivers digital sound – ...

Abstract: In this letter, a 1.7–6.5-GHz reactively matched power amplifier (RMPA) is designed using a 0.2-$\mu $ m gallium nitride (GaN) high-electron mobility transistor (HEMT) process. To achieve an ...

Abstract: Carbon nanotubes (CNTs), as a 1-D material, have become a favorable material for replacing Silicon to continue Moore’s law. Herein, we propose a gate-all-around cold source FETs (CSFETs) ...
