Design an emitter$-$coupled pair differential amplifier suitable for discreteimplementation and having the following specifications:a$.$ Direct $-$ coupled differential input.b$.$ Ac$-$coupled single$-$ended outputc. RL $=1$ kgd$.$ Output amplitude capability of $2$ V peake. Avds $=10($nominal value$)$f$.$ Half$-$power bandwidth from $1$ Hz to at least $1$ kHz$.$g$.$ CMRR $=80$ dB minimum from $1$ Hz to at least $1$ kHz$.$The transistors to be used are assumed to be identical and to have the following parameters:P$=15=100$ AVA $=$ VAF $=100$ V $($Early voltage$)$The available power$-$supply voltages are Vcc $=+15$ V and VEE $=-15$ V$.$
