it is not 众所周知 that the dynamic circuit consume more power than the
static circuit. Both of the designes have its own adantages and
disadvantages in low-power consideration.
In the static circuit, the output of one gate can be changed during a
single clock cycle, which is know as "glitch". The glitch will increase
the power consumption while the dynamic circuit can elimenate the glitches.
There is short circuit current in the static circuit. When the rise time
and fall time is not matched, this
