Four-value heat-insulating dynamic D trigger

The invention discloses a four-value heat-insulating dynamic D trigger. The D trigger comprises a character computing circuit, a character sampling circuit and a logic signal generating circuit, wherein the character computing circuit mainly comprises first, second, third and fourth sub-character computing circuits; and the logic signal generating circuit mainly comprises a 0-3 logic signal generating circuit and a 1-2 logic signal generating circuit. The trigger is characterized in that: the four-value heat-insulating dynamic D trigger designed through clocked heat insulation technology and multi-threshold MOS tube control technology mainly comprises the character computing circuit and the logic signal generating circuit; and the logic signal generating circuit is controlled by the character computing circuit to generate a four-value logic signal. The circuits of the D trigger sample the input signal through a clocked NMOS tube, and the output load realizes assignment and energy through a sampling value, the bootstrap-operated NMOS tube and a follow power clock with a cross storage type structure. The D trigger effectively reduces the power consumption and improves working reliability of the circuit on the premise of guaranteeing the correct logic function of the circuits.
