Vcc (1+) 12V v1- Rc1 Q1 NPN Q2 NPN Rc2 v2 IEE=100microamps REE=250k Fig. P2.24 PNP Q3 R 24k vo Vee -12V 2.24 Consider the fledgling Op Amp of Figure P2.24. The transistors all have ß = 100. (a) for the DC analysis, let v1 =v2 = vo = 0 and determine all Q points and values required for Rc1 and Rc2 to ensure Q1 = Q2. (b) Using the half circuit approach, sketch the ac circuit for the differential mode and for the common mode, (c) find the differential mode voltage gain, the common mode voltage gain, and CMRR(dB).
