Consider the following amplifier below.

We will consider $3$ stages of the amplifier in this homework. Two common emitter amplifiers are followed by a class AB amplifier, which is a power amplifier. Use $2$N$3904($for $2$N$4401)$ and $2$N$3906($or $2$N$4403)$ for the BJT transistors.

Compute the dc currents and dc voltages corresponding to base, emitter and collector in all $3$ stages.

Compute the overall voltage gain $($Av$),$ input resistance $($Rin$),$ and output resistance $($Rout$).$

Build the complete circuit using the transistors, resistors, capacitor and DC power supply.
