ABSTRACT:
A delay circuit includes current sources, switches, a transistor switch, a charging unit and a comparator. Each of the switches is provided for receiving an enable signal to activate and convey one of the current sources. The transistor switch is activated for pulling down voltage of an operating node coupled to the switches. The charging unit provides an operating voltage for the operating node based on one of the current sources when the transistor switch is deactivated and one of the switches is activated to convey one of the current sources to the charging unit. The comparator is provided for comparing the operating voltage with a reference voltage.
