摘要： Systems and methods to achieve a charge pump for generating from single supply voltage energy efficient supply voltages that are symmetrical around ground voltage have been disclosed. The charge pump requires two flying capacitors only. The charge pump generates positive and negative supply voltages following a 1/N ratio of Vdd voltage, i.e. +−Vdd/N, and can be generalized to generate +/−Vdd/2N voltages. This is especially useful for supplying class-G amplifiers.

摘要： Systems and methods to achieve a charge pump for generating from single supply voltage energy efficient supply voltages having a value of ±1/6 Vdd, ±1/5 Vdd, ±1/4 Vdd, ±1/3 Vdd, ±1/2 Vdd or ±1 Vdd that are symmetrical around ground voltage have been disclosed. The charge pump requires two flying capacitors only. The charge pump generates positive and negative supply voltages following a 1/N ratio of Vdd voltage, i.e. +−Vdd/N, and can be generalized to generate +/−Vdd/2N voltages. This is especially useful for supplying class-G amplifiers with a voltage or power, which is just enough e.g. for an audio signal to be correctly generated at the output of the amplifier.
