Common Emitter Amplifier Circuit Working & Its Characteristics

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. WebMar 21, 2024 · Here is how it works: The first stage is a fairly ordinary swamped common emitter amplifier using two-supply emitter bias. It also uses a Darlington pair to maximize the input impedance. Because the base current is so low, the DC drop on R B could be small enough to ignore so we may dispense with the input coupling capacitor. WebMay 31, 2024 · NPN transistors are used in the Darlington pair circuits for amplifying weak signals. NPN transistors are used in applications we need sinking current. NPN transistors are used in some classic amplifier circuits, the same as ‘push-pull’ amplifier circuits. NPN transistors are used in temperature sensors. durga kavach in hindi mp3 download
