Abstract
A voltage charge pump circuit with boost capacitor segments and boost delay chain structures are provided. The voltage charge pump circuit comprising a plurality of boost capacitor segments each of which is individually controlled by a respective signal line of a boost delay chain structure.
Claims15
A method comprising enabling of individual boost capacitor segments coordinated with delays, and charging an output device by a boost device in each of the individual boost capacitor segments,
- wherein a first line of signal lines of a boost delay structure comprises a NAND gate in series with a first inverter, and
- subsequent signal lines of the signal lines of the boost delay structure comprise a pair of inverters in series with a single input and a second NAND gate in series with a second inverter for corresponding boost capacitor segments of the boost delay structure.
