Common Emitter Amplifier : Working and Its Applications

WebMar 17, 2024 · The transistor is also what makes amplifiers work. Instead of having just two states (ON/OFF) it can also be anywhere in between “fully on” and “fully off”. That means a small signal with almost no energy can control a transistor to create a much stronger copy of that signal in the collector-emitter (or drain-source) part of the transistor. WebSince the emitter is always roughly 700mV below the base, we also call this "emitter follower" because the emitter output follows the base input. Three terminals means three types: common emitter, common base, common collector/emitter follower. This applies to a MOSFET as well, common source, common gate, common drain/source follower. WebFeb 10, 2024 · To work as an open switch, a BJT operates in cut-off mode, here there is zero collector current, meaning ideally zero power is consumed by the BJT. On the other hand, to work as a closed switch, a BJT works in saturation mode, there are a high collector current and zero collector voltage, meaning ideally there is zero power consumed by the BJT. honda hrn 166 owners manual
