This paper presents a DC-DC converter circuit with four operation modes which can be used for energy harvesting in the IoT. When the input voltage varies in a wide range, the circuit is not disturbed and smooth transition is achieved. It is implemented in SMIC 0.18 um CMOS process and the Cadence Spectre simulation tool is used for system-level and module circuit simulation verification. The simulation results show that the converter operates with a wide input voltage range from 0.4V to 3.3V, 1.8V output voltage, maximum load current of 100mA and switching frequency of 1MHz.
