Abstract
A charge pump regulator circuit includes an oscillator and one or more charge pumps. One or more oscillating signals are generated by the oscillator. Each oscillating signal has a peak-to-peak amplitude that is variable dependent on a variable drive signal. For some embodiments having multiple oscillating signals, each oscillating signal is phase shifted from a preceding oscillating signal. For some embodiments having multiple charge pumps, each charge pump is connected to receive a corresponding one of the oscillating signals. Each charge pump outputs a voltage and current. For some embodiments having multiple charge pumps, the output of each charge pump is phase shifted from the outputs of other charge pumps. A combination of the currents thus produced is provided at about a voltage level to a load.
