Design a differential amplifier using BJT's to provide a differential gain of 65. The bias current source should be 2.5 mA. Follow the fully differential amplifier with a differential input single ended output amplifier with an additional gain of 23. Bias this stage at 5 mA. Use ± 15 V power supplies and bias points that maximize the output swing range while meeting all other criteria. Calculate CMRR of the amplifier. Include schematic.
