WebMar 3, 2024 · BJT is the short form of Bipolar Junction Transistor, it is a solid-state current-controlled device which can be used to electronically switch a circuit, you can think of it as your normal Fan or Light switch, but instead of you turning it on manually it can be controlled electronically. Technically speaking, BJT is a three-terminal device with ...

WebMay 12, 2024 · The BJT is typically operated in one of three broad domains: cutoff: The base-emitter voltage is below some assumed threshold. For example, one might assume values below V BE ≤ + 400 mV for a silicon NPN. ( V BE may be forward-biased, but only a little. It can also be reverse-biased.) WebMar 1, 2024 · The transistor is not active but passive element; the only thing that it can do is to dissipate power. So, the transistor is not amplifying but attenuating element. It is just a "resistor" (non-linear, electrically controlled but still a resistor) that decreases the current. The true amplification is impossible; so there are no real amplifiers.
WebFeb 1, 2024 · The current flow through the BJT (Ic) is controlled by the size of the base current (Ib). Every BJT has a particular ratio between the size of this 'collector' current and the 'base' current which is called current gain (beta). Unless you really want to know the physics of the BJT forget about terms such as majority carriers, minority carriers ...
