Charge-pump topology doubles voltage

Michael Dunn has designed a circuit that is able to double the input voltage and breaks DC path. I once needed a voltage doubler circuit with no DC leakage path between input and output, and ended up devising this unusual 556- (dual 555 timer) based circuit with a "floating" voltage output.
