Unlike with BJT transistors that need a constant current flow, you only need to charge a gate once for the FET to remain open for a fair bit – and it’s such a small amount of charge that you ...

For the BJT and FET (either JFET or MOSFET) of either polarity (NPN or PNP, n-channel or p-channel), corresponding configurations are listed in the following table. The analog between emitter-source, ...

This is unlike the FET where the gate drive never sees the FET’s drain current. This puts more stress on the flyback controller’s base drive. When selecting a flyback controller for this design, make ...

Here’s an N-FET, used in the exact same configuration as a typical BJT is, except instead of a base current limiting resistor, we have a gate-source resistor – you can’t quite solder the BJT ...

Chapter 10: BJT Current sources. Chapters 5 and 6: FET configurations, models, and amplifiers – will discuss dc and ac models for FET amplifiers, selection of Q-point (active operating point) for dc ...

The converter described below, based on a silicon bipolarjunction transistor (BJT), can operate at as low as 250 mV, which is probably a record for a converter not based on a JFET or germanium ...

Also called a "bipolar junction transistor" (BJT), it is one of two major transistor categories; the other is "field-effect transistor" (FET). Although the first transistor was bipolar and the ...

This module brings together the underlying physical principles of BJT, JFET and MOSFET devices to show how structural decisions in device design affect performance as a circuit element. Basic circuit ...
