Abstract
A low power switched decoupling capacitor circuit is proposed to suppress on-chip resonant supply noise. Compared to previous analog techniques, the proposed digital implementation achieves a 9X reduction in quiescent power with improved tolerance to PVT variation and tuning capability for optimal switching threshold. Measurements from a 0.13 mum test chip show an 11X boost in effective decap value and a 9.8 dB suppression in resonant supply noise by using the proposed circuit.
