PHASED-ARRAY CHARGE PUMP SUPPLY

摘要

A charge pump system and method that may provide large supply voltages and currents with reduced ripple voltage at reduced ripple frequency. The charge pump system may include an array of charge pumps and a delay pipeline. The array of charge pumps may include a plurality of charge pumps. The delay pipeline may include a plurality of delay elements. The delay elements may respond to a global trigger signal to output a trigger signal to the array of charge pumps. Respective charge pumps may fire in response to the trigger signal.
