Free QuoteSupply noise is a critical problem for the robust operation of integrated circuits at ultra low voltage regimes. Although decoupling capacitance is a traditional solution, the reduction of gate capacitance at subthreshold voltage can cause area overhead. In this paper, we propose a decoupling capacitor design strategy to reduce area overhead.

INTRODUCTION A capacitive power supply is a very low-cost AC/DC converter without a transformer or switching components. With a very small parts count, these circuits can provide a DC voltage for low-power applications. In addition, because no high-speed switching is occurring, no EMI noise is generated.
Capacitive power supplies typically have a low power factor. By the equation of state for capacitance, where, the current is limited to: 1 amp, per farad, per volt-rms, per radian (of phase). Or amps, per farad, per volt-rms, per hertz.
