Abstract
An integrated circuit built-in type power delay circuit which is capable of supplying a stable supply power to each circuit of the integrated circuit by generating a supply power control signal voltage after a predetermined time. The circuit includes a receiving unit for receiving a supply voltage VDD and charging the same, a supplying unit for supplying a current, an inverting unit for inverting an output value from the charging unit, a switching unit controlled in accordance with an output value from the inverting unit for switching an output from the current supply unit, a current regenerating unit for receiving a control of the switching unit and discharging an output value from the charging unit, an electric potential value conversion unit controlled by an output value from the inverting unit for converting an output value from the charging unit into a low level, and a buffering unit for receiving an output value from the inverting unit for buffering the output value and outputting a non-inverted signal.
