9.101 For the folded-cascode differential amplifier of Fig. 9.38, find the value of VBIAS that results in the largest possible positive output swing, while keeping Q3, Q4, and the pnp transistors that realize the current sources out of saturation. Assume V CC = VEE =5 V. If the dc level at the output is 0 V, find the maximum allowable output signal swing. For I = 0.5 mA, βP =50, βN =100, and VA =100 V find G m, Ro4, Ro5, Ro, and Ad.
