Hi,
In a textbook the emitter follower is depicted as a voltage series negative feedback amplifier and a current series negative feedback amplifier as wel l. Difference between the two circuits shown is only that the one, which is a current series feedback amplifier uses another load resistor coupled to the emitter resistor using one capacitor that is the load resistor and emit ter resistor are in parallel only for ac and for dc load resistor is absent . In the one, which is shown as voltage series negative feedback amplifier doesn't have any load coupled to emitter resistor and output is taken acros s emitter resistor only. Does the coupling capacitor changes emitter follow er from a voltage series to current siries negative feedback? Please clarif y.
Thanks and regards, Koyel
