Consider the design of the class AB output stage of Fig. 12.23 for the following

Chapter 12, Problem 12.48

(choose chapter or problem)

Consider the design of the class AB output stage of Fig. 12.23 for the following conditions. The stage is operated from 2.5-V power supplies and is required to provide a minimum output voltage swing of 1.5 V while supplying a maximum current equal to 10 times the quiescent current IQ. Assume that QN and QP are matched and Q1 and Q2 are matched, that all devices have |Vt| = 0.5 V, and that in the quiescent state all transistors are operated at the same overdrive voltage. What is the value of VOV required, and what VGG is needed?
