You are to compensate the two-stage opamp of Fig. 6.3 when driving a load capacitance of .


a. Following the procedure in section 6.2.2, select the values of and in the compensation network assuming a unity-gain feedback configuration.


b. Keeping the same values of and as in part (a), what is the maximum load capacitance that can be driven while maintaining at least phase margin?


c. Modify , , and to increase the slew rate by 30% while maintaining the same phase margin and total power consumption. Estimate the resulting impact on the opamp’s dc gain.
