You need to calculate the effect of charge sharing. All inputs are driven from other domino gates and only one input can switch during evaluation. Assume C diff = C gate = 2 fF/ µ m. Let V DD = 1V, µ n / µ p = 2, V TP = 0.2V, V TN = 0.2V, unit/reference inverter W p / W n = 2 µ m / 1 µ m. A D V DD Clk B C Clk F X c. Given the relative transistor sizes from (b) and keeping the transistor sizes parameterized (e.g.
