The goal of this series is to maximize the voltage gain of the single transistor ... amplifiers—gutless amplifiers are depressing. Perhaps you do not need all this voltage gain—in that case, it can be ...

Imagine for a moment a simple transistor circuit involving a single NPN transistor ... simple transistor AC amplifier. The classic transistor amplifier circuit then has a pair of resistors in ...

There is so much to learn about the single-transistor ... for low power amplifier transistors that dissipate less than about 100mW. R1, 2 & 3 form the base divider. The juncture of R2 & 3 is bypassed ...

The collector circuit of a transistor amplifier can either be a very low resistance or a reactive circuit with a zero resistance DC path. By comparison the impedance of the base circuit on the ...
