Abstract:In modern integrated circuits (ICs), integrating workload-agnostic multiphase switched-capacitor (SC) voltage converters on-chip is an effective way to reduce the transient response time, improve the security, and boost the power efficiency. However, a stochastic and unbalanced active sequence within the multiphase SC converter may undermine the corresponding output voltage ripple significantly. In this paper, a novel algorithm that is based on Fourier transform is capable of efficiently mitigating the amplitu… Show more
