In static circuits, at every point in time (except when switching) the output is connected to either GND or VDD via a low resistance path. fan-in of n requires 2n (n N-type + n P-type) devices
Dynamic circuits rely on the temporary storage of signal values on the capacitance of high impedance nodes. only requires n + 2 (n+1 N-type + 1 P-type) transistors
Once the output of a dynamic gate is discharged, it cannot be charged again until the next precharge operation. Inputs to the gate can make at most one transition during evaluation.

Output can be in the high impedance state during and after evaluation (PDN off), state is stored on CL 8
Overall power dissipation usually higher than static CMOS no static current path ever exists between VDD and GND (including Psc) no glitching higher transition probabilities extra load on Clk
PDN starts to work as soon as the input signals exceed VTn, so VM, VIH and VIL equal to VTn
Logic function is implemented by the PDN only number of transistors is N + 2 (versus 2N for static complementary CMOS)
Full swing outputs (VOL = GND and VOH = VDD) Non-ratioed - sizing of the devices does not affect the logic levels Faster switching speeds

Coupling between Out and Clk input of the precharge device due to the gate to drain capacitance. So voltage of Out can rise above VDD. The fast rising (and falling edges) of the clock couple to Out.
