Dynamical element with ANDOR functions of
the Domino type consists of two series CMBS inver
tors . The first invertor is clockforwarded (logical)
with a builtin logical block on
type transistors with
a given function. The second CMBS invertor is static.
On the halfclock CL = 0, the charge of node capaci
occurs through a precharged
to the power voltage. In the working halfclock CL = 1,
the charge on the
capacitance depending on pre
liminary fed logical signals either is preserved (at the
exit element—0) or decreases to the ground potential,
and 1 forms at the element exit (the load capacitance
(the supply voltage
). The shortcoming of the circuit
technology of the Domino type is the presence of a
statictype invertor and an insufficient number of the
degrees of freedom in the process of engineering .
In the static CMBS invertor at the region
the modulus average of the liminal transistors’ voltage)
there is a through current; as a result, only part of the
current is used in overcharging capacity intensity, so
the switching time and the power consumption rises.
For MDS (metaldielectric semiconductor) transis
tors with a short bus (less than 150 nm) under a small
it is common to have preliminal cur
rentsource voltages. Under CL = 1 the charge on the
capacitance under the realization of the function,
that equals 0 can be lowered by the amount of the lim
inal voltage of an
type transistor and on the exit
equivocation can occur. To make the use of function
under cascade reliable, the Dominotype element is
