Connect a circuit using wire, a 9-V battery, an LED, a resistor, and a microammeter ... allow you to observe the operation of a transistor as an amplifier, just as Walter Brattain did at Bell ...

The base resistor chain from the ... amplifier rather than a current amplifier, its input impedance is many orders higher than that of a bipolar transistor, and thus you will find FETs used ...

and class AB audio amplifier. The devices are a little archaic by today’s standards, with comically low-gain germanium transistors and passives from the Ark. Injecting a signal reveals that the ...

Two papers at the International Solid-state Circuits Conference tackled ultra-low power on-chip temperature sensing, one using an npn transistor and ... loop was picked to read the resistor, ...
