Colector resistance in an emitter follower circuit serves to place a limit on how much current can be supplied by the transistor. Often, the resistor is sized so that a short circuit in the load does not cause the transistor to fail.
The (Class C, Common Collector) Emitter Follower is used to amplify the available current from a voltage driving circuit that might be disturbed by the load impedance.If the actual voltage value is...
The gain of a common-emitter amplifier is collector resistor divided by emitter resistor, or hFe, whichever is less. Since hFe depends on temperature, designing the amplifier to be dependent on...
By adding capacitors or inductors in series (typically lower power) or parallel (higher power power factor correction); the choice of capacitor or inductor depends on whether the reactive resistance...
A: Any transistor of either polarity can be used as an emitter follower, The purpose of an emitter follower is to provide current to the load since it cannot provide any voltage gain
