The easiest way to understand how MOSFETs work is to compare them with PNP and NPN transistors and show them in similar circuits. The advantage of a MOSFET is this: It requires very little current (almost zero current) into the gate to turn it ON and it can deliver 10 to 50 amps or ...
Solved: Hello, i am currently working on a project where i have to make an electronic card using a PSOC programmer to be able to make a timer and a
So for each of these types of transistor, there are at least two ways to draw it. Bipolar Junction Transistors (BJTs) BJTs are three-terminal devices; they have a collector (C), emitter (E), and a base (B). There are two types of BJTs -- NPNs and PNPs -- and each has its ...
The transistor works like an electronic switch. It can turn a current ON and OFF. A simple way to think about it is to look at the transistor asa relaywithout any moving parts. A transistor is similar to a relay in the sense that you can use it to turn something ON and OFF. But a...

The definition of “saturation region” or “ON mode” when using a bipolar NPN transistor as a switch as being, both the junctions are forward biased, IC = Maximum, and VB > 0.7v. For a PNP transistor, the Emitter potential must be +ve with respect to the Base. This is the working...
A negative Base voltage on a PNP transistor will allow current to flow.Here's two transistor circuits that look and function very much like tube amp circuits. The first is the transistor common emitter amplifier:Tube triode amp circuit on the left, transistor common emitter amp on the right....
One 7CT1N will test a PNP and while it is in place the second 7CT1N can be used to select a transistor that is closely matching as pair. There are two curves worth paying attention when comparing two complementary transistors. The first Step in the curve closer to zero should be ...
For an LDO to emulate a load switch, it must have a way to force operation in dropout mode. Adjustable LDOs have a feedback pin that enables you to put the device into dropout mode (full-on output). An LDO with field effect transistor pass element has low dropout voltage and low ...
Transistors have a MASSIVE impact on the character and tone of your fuzz pedal. You may find that when you plug your guitar into your fuzz that you don’t like the transistor you selected. This is why we socket the transistors – so that you can swap these out easily. This way you ca...
