Abstract
The goal of this paper is to show the performance of the DC–DC conversion technique of the Dickson charge pump and the comparative analysis of the inductor-based charge. The converter analysis, that involves the Dickson charge pump, is built on a novel series inductor and parallel capacitive construction, and it is profitable for energy harvesting applications. In this paper, we have shown the use of an inductor in five-stage Dickson charge pump to generate an output voltage of 8.76 V with 20 Ω resistive load and a 50 MHz external frequency. The least drop is at output voltage capacitor that is used as an energy storage element. In the experiment, the integrated charge-up converter is based on LC tank features. This unique simulation study is done in the T-Spice 0.18 μm CMOS process using an input voltage of 1.8 V, using high Vt and low oxide thickness Tox for reducing threshold voltage drop at latter stages.
