of each stage, in order to fit all levels have appropriate operating point of stage base, Step by step the collector potential increases, so reducing the final output voltage range. In order to solve this problem, in practice, it can be used in conjunction with NPN and PNP transistor to reduce the post-stage DC potential, as shown in FIG. Figure (8) shows an NPN cvri) and PNP transistor (VT2) wish, is used to reduce the subsequent stage (VT3) potential. Alternatively, you can use emitter follower, stage amplified voltage diode to reduce a DC potential of the circuit. Figure l-43 (b) shows the use of emitter cvn) is used to reduce the subsequent stage (, rr3) potential.
