  • Abstract
    This work presents a switched-capacitor power converter (SCPC) with a power density of 38.6mW/mm2 at 81% efficiency and 3.8mV output voltage ripple (ΔV0) in baseline 90nm CMOS. The design implements two different conversion ratios to maximize efficiency for a wide range of input voltages, and the use of 41 phases results in a very low output voltage ripple and low input current spikes.
