Bjt as an amplifier working
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. WebMay 22, 2024 · This amplifier is based on a two-supply emitter bias circuit. The notable changes are the inclusion of an input signal voltage, Vin, and a load, RL. So that these components do not alter the bias, we isolate the input and load through the use of coupling capacitors Cin and Cout.
