Consider the circuit in Figure.
(a) Determine R1 such that IREF = 0.20 mA.
(b) Determine the values of R5 and R6 such that the maximum currents in Q5 and Q6 are 0.12 mA.
(c) Consider A = B = 0. What is IQ? Using the results of part (a), find RC1 so that vO1 = -0.7 V.
(d) Consider A = B = -0.7 V. What is IQ? Using the results of part (a), find RC1 so that vO2 = -0.7 V.
