A Subthreshold Operation Series-Parallel Charge Pump Incorporating Dynamic Source-Fed Oscillator for Wide-Input-Voltage Energy Harvesting Application

This work proposes a CMOS reconfigurable charge pump (CP) for a low-voltage energy harvesting system. It utilizes the low effective resistance from the parallel CP to enhance its power conversion efficiency (PCE). The CP exhibits an adaptive configuration with different stages depending on the input...
