Abstract
An electrical system for generating arbitrary voltage waveform includes a power supply unit for providing a supply voltage to the electrical system. One or more charge pumps are in electrical communication with the power supply unit. Each charge pump generates a voltage. The electrical system also includes a plurality of switches, a first switch among the plurality of switches coupled between a ground and an output terminal, other switches among the plurality of switches coupled between the one or more charge pumps and the output terminal. A control circuit is in electrical communication with the power supply unit, the plurality of switches and the one or more charge pumps, and is operable to control the voltage generated by the each charge pump and the plurality of switches. Voltages from the one or more charge pumps additively result in a variable output voltage that generates an arbitrary voltage waveform.
