Abstract—On-chip resonant supply noise in the mid-frequency
range (i.e., 50–300 MHz) has been identified as the dominant
supply noise component in modern microprocessors. To overcome
the limited efficiency of conventional decoupling capacitors in re-
ducing the resonant supply noise, this paper proposes a low-power
digital switched decoupling capacitor circuit. By adaptively
switching the connectivity of decaps according to the measured
supply noise, the amount o
