Abstract:
1. A charge pump system comprising: first means, including an input and output node, for transmitting, without substantial loss, an input voltage on the input node to the output node during a first phase of a first clock, and for adding a first predetermined voltage to the voltage on the output nodes during a second phase of the first clock; and second means, including an input and output node, the input node being connected to the output node of the first means, for transmitting, without substantial loss, a voltage on the input node to the output node during a first phase of a second clock, and for adding a second predetermined voltage to an output node during a second phase of the second clock, the first phase of the first clock being aligned with the second phase of the second clock and the second phase of the first clock being aligned with the first phase of the second clock, such that the voltage at the output of the second means is substantially near the sum of the input voltage and the first predetermined and second predetermined voltages during the second phase of the second clock.
