D13.26 For the circuit in Fig. 13.30, determine the value that IREF should have so that QN and QP have a quiescent current IQ = 0.4 mA. Assume that the transistor areas are scaled so that ISN/IS10 = 10 and IS7/IS11 = 2. Let I = 10 µA. Also, if iL in the direction out of the amplifier is 10 mA, find iP and iN.
