[Paulo] just tipped us about an Excel based high frequency transistor amplifier calculator he made. We’re guessing that some of our readers already are familiar with these class A amplifiers ...

Just over six inches tall, this portable calculator certainly surpassed the all-transistor calculator released just a year earlier -- that calculator weighed 55 pounds and cost $2,500.

If transistors could replace vacuum tubes in the phone system, then they certainly could replace them in computers too. The army, with its need for ever-faster and more efficient calculations ...

The researchers, led by physical chemistry professor Peng Hailin, said their self-engineered 2D transistor could operate 40 per cent faster than Intel and TSMC’s cutting-edge 3-nanometre silicon ...
