  • It's a capacitor that goes between VDD and GND in parallel with the rest of your logic gates. When your logic gates draw a high amount of current, this capacitor provides extra charge close to that circuit. When your logic gates aren't drawing current, the capacitor charges up to maximum capicity and sits there waiting to be discharged.
