So they are used for the purpose of … softube bus processorWebSince 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. softube chandler limited curve benderWebEmitter follower is a case of negative current feedback circuit. This is mostly used as a last stage amplifier in signal generator circuits. The important features of Emitter Follower are It has high input impedance. It has low output impedance. softube compressor limiterWebJan 11, 2010 · Emitter Follower Voltage Regulator. With our previous voltage regulator with the zener diode, we had the problems of the zener diode wasting power and needing a high power diode if there was a lot of current going through the diode. If we add an emitter-follower, we can use a much smaller diode and less current to achieve the same effect. softube console 1 ebayWebEmitter follower.
