<p>A circuit for maintaining the potential of a node (ND) of a MOS dynamic circuit (1) includes a repetitive charging circuit (4) which comprises a circuit (41, 42, 45) to supply a charging current to the node from a point the potential of which is raised higher than a supply source voltage (Vcc) during a predetermined period by the application of a clock signal (S3) whereby the potential of the node is maintained at a predetermined potential (Vnd) higher than the supply source voltage, without supplying a steady current to the node, until a reset signal (S2) is applied to the MOS dynamic circuit. The circuit comprises a number of MOS field-effect transistors (41, 42) and a MOS capacitor (45), the higher potential point being formed at a connecting point of the electrodes of the MOS field-effect transistors and one electrode of the MOS capacitor.</p> |
