ABSTRACT:
A capacitor-coupling acceleration apparatus is an accelerating circuit capable of being applied to interconnect lines in an integrated circuit in order to reduce delay owing to parasitic resistance and capacitance of the interconnect lines in the integrated circuit. The apparatus can be disposed between the interconnect lines. When a signal transmitted on the interconnect line has a change from a low-level voltage to a high-level voltage, the apparatus detects the voltage level change of the signal and provides a charging loop to charge the interconnect line, thereby accelerating the change from the low-level voltage to the high-level voltage. When a signal on the interconnect line has a change from the high-level voltage to the low-level voltage, the apparatus detects the voltage level change of the signal and provides a discharging loop to discharge the interconnect line, thereby accelerating the change from the high-level voltage to the low-level voltage.
