Delay circuit using capacitor and transistor.

摘要

A delay circuit comprising at least one capacitor (209,210) with one electrode thereof is connected to a fixed potential (GND), a signal transmission line (212), and at least one switch means (205,208;211,206,207) between the other electrode of the capacitor and the signal transmission line (212). The switch means makes electrical connection or disconnection between the capacitor and the signal transmission line (212) in accordance with an actual supply voltage (Vdd) value.
