$$Perform an approximate DC analysis $($assuming $\backslash$beta $>>1,$ so that the base current of every transistor can be ignored$)$ to calculate the DC collector currents and voltages in the circuit.

$$Find the quiescent power dissipation for each transistor and the voltage gains of each stage.

$$Calculate the AC characteristics of the circuit, such as$,$ total voltage gain $($dB$),$ input and output impedance, CMRR in dB $($Common Mode Rejection Ratio$),$ maximum output voltage swing. Assume $\backslash$beta $=400,$ and Early voltage $=200$ V$.$

$$Ideally$,$ an op$-$amp should have a very high input impedance $($M$),$ low output impedance $(10-100),$ very high voltage gain $(>100,000=100$ dB$),$ and a very high CMRR $(>100$dB$).$ Is this the case with this simple circuit?
