发明名称 Low ripple charge pump
摘要 A charge pump circuit may have multiple charge pumps. Each charge pump may have an output. The outputs of the charge pumps may be connected to a common output terminal for the charge pump circuit. The charge pump circuit may produce an output voltage at the output terminal. The output voltage may be monitored by a charge pump regulator circuit. The charge pump regulator circuit may produce a control signal based on the measured output voltage. The control signal may be processed by register and logic gating circuitry and may be used to generate a sequential set of slave charge pump enable signals. The slave charge pump enable signals may be used to sequentially enable the charge pumps to progressively increase the strength of the charge pump while exhibiting reduced ripple.
