What are the single-ended slew rates of the fully differential folded-cascode and current-mirror opamps, assuming and the current densities are the same as those of Example 6.9 and Example 6.11, respectively? Calculate the slew rates in both the positive and the negative directions. Assume the load capacitances are 10 pF between each output and ground. For the folded-cascode design, assume the clamp transistors and of Fig. 6.28 have not been included. Also, assume the current sources biasing the output stages do not change during transients.
