Streamlined Fibonacci Charge Pump

Abstract

This paper is devoted to questions of the efficiency increase of the Fibonacci charge pump (FCP). The main attention is dedicated to discovering the mechanism of the power losses in the given FCP structure. The FCP after reduction of the power losses has a flatter efficiency characteristic than the original FCP structure. Thus, the efficiency of the streamlined FCP is a greater than 70 % in a wide range of the output current (from 1.5 mA to 10 mA approx..) when the input voltage is 3 V and the designed output voltage is greater than 30 V.
