The answer comes from the gate being insulated either by a depletion region in a JFET or by an insulating layer in a MOSFET. A FET is a voltage amplifier rather than a current amplifier ...

These are all under the transistor umbrella, but when people say “transistor”, they usually mean BJT, and when people say “FET”, they usually mean “MOSFET”. You can imagine a FET as a ...

In this module on BJTs (bipolar junction transistors), we will cover the following topics: BJT Device structures, Energy band diagrams, Active bias, Leakage current, Recombination in base, Hoe ...

Also called a "bipolar junction transistor" (BJT), it is one of two major transistor ... which consume less power (see FET and MOSFET). Bipolar transistors are available as individually packaged ...
