Thus the three basic bipolar transistor circuit configurations have ... A FET is a voltage amplifier rather than a current amplifier, its input impedance is many orders higher than that of a ...

Enter an old Radio Shack P-Box stereo amplifier kit. After a few modernizations and tweaks, the result is an 8-transistor stereo ... but with their high leakage current and low thermal ...

Safety: The current in this circuit is small enough to perform ... These circuits will allow you to observe the operation of a transistor as an amplifier, just as Walter Brattain did at Bell ...

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 ...

(Image: Azal Alothmani, Lund University) When working as an amplifier, a transistor transforms a small input current into a bigger output current. As a switch, it can be in one of two distinct states ...
