Question

and REEo, what is the required lg, assum- ing negligible base currents? Hint: increasing E to raise a wil also lower Voi and Vo and thus bring the BJTs closer to saturation. The most critical instants are when Vol and VO2 reach their negative peaks. (b) Assuming r,- , what is the ensuing gain a? What are the total signals Voj, Vo, and voD? RC1 Rc2 01 02 V2 V11 4.42 We wish to design an EC pair of the type of Fig. P4.39 so that when driven with Vn- (10 mV) cos ωt and v12-0 it produces the largest possible output signal under the constraint that neither collector voltage ever drops below O V thus avoiding forward-biasing the B-C junctions of the BJTs.
