Patent ID: 6909319

Claim:
A charge pump system comprising: first pump 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 signal, and for adding a first predetermined voltage to the voltage on the output node during a second phase of the first clock signal; and second pump 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 signal, and for adding a second predetermined voltage to an output node during a second phase of the second clock signal, the first phase of the first clock signal being aligned with the second phase of the second clock signal and the second phase of the first clock signal being aligned with the first phase of the second clock signal, 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 signal; clock signal generation means for providing an oscillating power signal; and threshold detection means for providing first and second clock signals in response to the oscillating power signal.
