Abstract
Charge pump circuit includes a plurality of boost capacitors. An output charge of the charge pump circuit is adjusted by selecting a number of the boost capacitors at least one of using a digital control word and programming of a wiring level. A method of boosting supply voltage uses a charge pump circuit. The method includes adjusting an output charge of the charge pump circuit by selecting a number of boost capacitors at least one of using a digital control word and by programming of a wiring level.
Claims24
A charge pump circuit comprising:
- a plurality of boost capacitors, wherein an output charge of the charge pump circuit is adjusted by selecting a number of the boost capacitors by at least one of:
- using a digital control word;
- and
- programming of a wiring level;
- and further comprising:
- a common input plate node coupled to the plurality of boost capacitors, wherein:
- in a precharge time, the common input plate node is precharged to ground;
- and
- in a transfer stage, the common input plate node is lifted to a power supply level.
A method of boosting supply voltage using a charge pump circuit, the method comprising:
- adjusting an output charge of the charge pump circuit by selecting a number of boost capacitors by at least one of:
- using a digital control word;
- and
- by programming of a wiring level,
- wherein, in a precharge phase, devices arranged in a first stage will precharge voltage nodes in response to the digital control word, when a clock signal of a second stage of the charge pump circuit goes high.
