Abstract:
Semiconductor devices are provided. The semiconductor device includes a charge controller, a delay unit and a discharger. The charge controller controls an amount of electric charges on a first node to output a drive signal through the first node. The delay unit includes a capacitor coupled to the first node and retards the drive signal to generate an output signal. A delay time of the drive signal is controlled according to an amount of electric charges of the first node. The discharger discharges the electric charges of the first node when the amount of electric charges of the first node is equal to a predetermined value.
