A fully integrated inductor-based 1.8-6-V step-up converter

To the authors knowledge, this is the first time that a paper demonstrates the feasibility of a fully integrated step-up converter based on inductive elements. The prototype is fabricated in the ST M8 0.18-/spl mu/m process, uses a supply voltage of 1.8 V, and provides an output mean voltage of about 6 V at 10 k/spl Omega/ resistive load with a 60-MHz external clock frequency.
