Perform an approximate DC analysis $($assuming $>>1,$ 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 $=400,$ 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?
