Abstract
An improved dynamic-type digital circuit provided with a level refresh means for refreshing a logic signal retained at a high impedance is disclosed. The circuit comprises a signal node, a control node, a voltage source, switching means coupled between the signal node and the voltage source, the switching means being controlled by a level of the control node, control means responsive to a level of the signal node for determining a level at the control node, capacitor means coupled to the control node at its one end and means for supplying the other end of the capacitor means with a control signal.
