[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 ...

but with their high leakage current and low thermal conductivity, he decided to convert it to work with silicon transistors. He also made some improvements to the push-pull bias circuit and ...

Transistors do not create electric current, they only control electric ... 3. How good an amplifier was your circuit? How much larger was the output current than the input current?

In this chapter we will study the transistor differential-amplifier circuit. This is a very important transistor circuit, as it is the basis of the operational amplifier (or op amp), one of the most ...

The first transistor was about half an inch ... This contraption was the very first semiconductor amplifier, because when a bit of current came through one of the gold contacts, another even ...

to develop high-electron mobility transistors (HEMTs) and amplifier circuits for highly efficient satellite communication ...
