| Abstract in different language: | An operation of electronic equipment is dependent on a power supply. Today, a trend of only one AC/DC adapter is used for supplying an electronic system. Thus, an electronic equipment with various power supply requirements uses some internal DC/DC converters. These DC/DC converters adjust input voltage to lower or/and higher value or generate a negative voltage. The classical DC/DC converters are based on inductors or transformers. These converters are too large and suitable for a higher output power. A charge pumps are a sufficient alternative to classical DC/DC converters for a lower output power and a smaller dimension. A well-known variant of a charge pump is Dickson charge pump. The output to input voltage ratio is a directly proportional to the number of Dickson charge pump stages. Thus, the number of stages can be a relatively high for low input voltage and required high output voltage. The Fibonacci charge pump is a suitable alternative to Dickson charge pump especially for a higher output to input voltage ratio. This article describes practical circuit solution of the Fibonacci charge pump. The key properties of the Dickson and the Fibonacci pumps are compared in this article, too. |
