Integrated circuits with decoupling capacitor circuitry are provided. The decoupling capacitor circuitry may include density-compliance structures. The density-compliance structures may be strapped to metal paths driven by power supply lines. Strapping density-compliance dummy structures in this way may increase the capacitance per unit area of the decoupling capacitor circuitry. Strapping density-compliance dummy structures in this way may shield the decoupling capacitor from nearby noisy signal sources.
