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 voltage. changing its voltage conversion ratio (VCR) to limit the output voltage under 1. https://www.roneverhart.com/Hot-Wheels-Ultimate-Octo-Car-Wash/
