What are the swing limits for each output of the differential amplifier in Fig. 12.2? Use |V_ov| = 0.2 V for all transistors and V_tn= ˆ’V_tp= 0.6 V. Assume V_DD= V_SS= 2.5 V, V_ic= 0 and γ = 0. Also, assume that the common-mode feedback circuit does not limit the output swing. What value of V_OCgives the largest symmetric differential output swing? What is the peak value of V_odin this case?
