Multistage Amplifier Circuit Diagram. This kind of coupling is also named as interstage coupling. If you need exactly 6 you can play a round with the resistance on the input.

15 is a graph of an input output characteristic of the amplifier circuit shown in fig. In dc coupled multistage cascaded common emitter amplifiers the output bias level of each stage increases to maintain the collector more positive than the base. Driven from one side is cc followed by cb.

A two stage complementary pair bjt amplifier circuit diagram is shown in figure 10 1 4.

Unlike complementary pair push pull amplifier circuits this circuit absolutely requires a preamplifier stage called a phase splitter comprised here by transistor q 1 and resistors r 3 and r 4. Multistage amplifiers vs rs rin1 a1 v1 rout1 rin2 a2 v2 ro2 rl v1 v2 source amp1 amp2 load vl multistage amplifiers are difficult to compute if the components are not unilateral. This kind of coupling is also named as interstage coupling. Hence they are replaced by multi stage transistor amplifiers.
