Suppose the BJTs in the transconductor of Fig. 5.38 have 5 200 and VA 5 50 V. Moreover, let I3 5 I4 5 0.1 mA, and suppose Is1 5 10Is3 and Is2 5 10Is4. The transconductor is now connected in the form shown concisely in Fig. P5.36, with the power supplies not shown to avoid cluttering. Calculate Rb, Rc, and Re if RE 5 250 V and RC 5 10 kV. Hint: exploit the symmetry of the circuit about the horizontal line joining B, E, and C in Fig. 5.38.
