The dynamic model of Figure 7.2.4 relates the switching speed to the charging and discharging time of the gate capacitor.
\[ f_{max} = \frac{1}{CV_{DD}} \nonumber \]
Thus, switching speed can be improved by
- increasing the on current of the transistors
- decreasing the gate capacitance by scaling to smaller sizes
- decreasing the supply voltage (thereby decreasing the voltage swing during charge/discharge cycles
