How many inverters are required in a fixed-taper design to minimize the propagation delay? What are the capacitances of those stages? What is the total delay the buffer contributes if 100ps is the delay of the gate driving the buffer? Hint: Besides class notes, the following references may be helpful: 1.H. C. Lin and L.
