(b) The logic gate from (a) needs to drive a capacitive load of 150 ff with a rise- time and fall-time of 0.5 ns. If the length of all transistors is 0.5 µm, calculate the required widths for all P-type and all N-type MOSFETs in your logic gate to achieve the required edge-speeds. Clearly show the calculation steps in your solution. Assume VDD = 5 V, K'n = 50 μA/V², K'p = 20 μA/V²
