The circuit in Figure 11.91 has two bipolar differential amplifiers incascade, biased with ideal current sources IQ1 and IQ2.Assume the transistor parameters are β= 180 and VA= ∞. (a) Design the circuit such that υo1 = υo2 =2 V and υo4 =6 V when υ1 =υ2 =0. (b) Determine the differential-mode voltage gains Ad1 = (υo1 − υo2)/υd and Ad= υo4/υd.
