Combination of grounded source and common emitter amplifier

Combination of grounded source and common emitter amplifier. The input impedance of the common emitter amplifier is in the range of l03fl, so it is difficult to be directly driven by a field effect transistor
. However, if a first-level emitter follower is used , it is used as the load Rtun as shown in the figure and is connected to the common emitter amplifier . Before
, it was easy to drive, as shown in the picture. This circuit adds an emitter follower stage in front of the output stage to obtain
current gain and is an example of a typical low output impedance.
