Abstract :
In this paper, we present a special ultra-low start-up voltage DC-DC boost converter that allows it to boost input voltage as low as 40mV to provide multiple regulated output voltages (4.1V and 5V) for low power wireless sensors applications by adopting different ratio of transformer and connection modes. Furthermore, the measured prototype can successfully drive a wireless humiture sensor node load when the humiture sensor transmits signal.
