Abstract

A new technique based on a ripple-voltage MPPT in combination with a 2-phase charge pump structure for autonomous miniature sensor nodes is proposed. Compared to earlier techniques, the proposed technique reduces the power consumption of the MPPT by 92 % to 2.9 nW. Furthermore, a series-parallel charge pump in a 2-phase structure is proposed that achieves a high accuracy with low input and output ripple-voltage, allowing a smaller input buffer capacitance.
