Assume a MOS transistor’s unity-gain frequency is approximately given by . Find an expression for in terms of and . Assume a single gain stage without compensation has a unity-gain frequency given by . Further assume that a comparator is realized by a cascade of three stages, each having a gain of –15. If three time constants are required for settling during the open-loop comparison phase, what is the maximum frequency of operation for the comparator? What is the resolution? You may assume that , , and that there are only -channel transistors in the signal path.
