Looking at the circuit it can be seen that although the emitter voltage follows that of the base, in DC terms it is actually less than that of the base by a voltage equal to the PN junction drop between the base and emitter. you will learn about multistage amplifiers. We have also explored and comprehensively developed the indirect feedback compensation theory for the two-stage as well as the multi-stage op-amps, The proposed indirect compensated op-amps exhibit significant improvements in speed over the traditional Miller compensated op-amps and result in much smaller layout size and lower power consumption.

Two Stage Cascaded Amplifier. As the emitter voltage follows that of the base, this means that the input and output are exactly in phase and not shifted by 180° as in the case of the common emitter amplifier.
Since the output at the source terminal is following the input signal, it is also known as Source Follower.
The emitter follower can be designed and electronic component values determined using the design flow below as a basis: The emitter follower circuit is particularly useful for applications where a input high impedance is required. This happens when an amp is driven to over-amplify a signal beyond its power rating.
