摘要： The present invention provides a method, apparatus, and system for rapid transition of a charge pump circuit from a low power state to a high power state. The charge pump circuit has at least one pump stage. The at least one pump stage includes at least a first capacitor coupled to a gate of a first switching transistor forming a boot node and at least a second capacitor coupled to an output node of the at least one pump stage. It is determined whether the charge pump circuit is in the low power state or the high power state. If the charge pump circuit is in the low power state, a first predetermined voltage and a second predetermined voltage that are different than the ground voltage level are applied to the boot node and the output node, respectively. If the charge pump circuit is in the high power state, the first predetermined voltage and the second predetermined voltage are removed from the boot node and the output node, respectively.

摘要： A double cascode protected switchable voltage source may be used to selectively provide positive or negative voltage sources, for example, to a flash memory. The positive supply may be connected through a PMOS pass device to a first cascode protection device. A negative supply may be connected through an NMOS pass device and an NMOS cascode protection device to an output. The circuits may be designed so that exceeding snapback limits and gate aided drain breakdown are less likely.

摘要： A method and apparatus for controlling a charge pump. A detection circuit is used to assert a detect signal when a power supply voltage exceeds a first threshold voltage and deassert the detect signal in response to a trigger. The detect signal is used to force a charge pump to operate in a mode that drives the capacitive node at its output to the target voltage with reduced latency. This is particularly useful for a device which may operate the charge pump in a reduced power mode which is designed to maintain the node voltage at reduced power rather than drive it to the degree necessary for reduced latency during power up.
