Dynamic regulation scheme for high speed charge pumps
摘要:
The present invention involves a charge pump including an input node coupled to receive an input voltage from a power voltage source and an oscillator unit generates a periodic enable regulator signal and a periodic reset signal. A regulator clock unit is coupled to the oscillator unit generating a precharge (PC) signal and a reset regulator signal in response to the enable regulator signal. A pump clock unit receives a master clock signal and generating a plurality of pump clock signals. A charge pump unit is coupled to the input node and is operatively controlled by the plurality of pump clock signals, and coupled to the an output terminal coupled to produce an output signal (VPUMP). A regulator unit is coupled to receive the VPUMP signal, the PC signal, the reference signal and the enable regulator signal, where the regulator unit is responsive to the enable regulator signal to operate in either a precharge mode or a regulation mode.
