Abstract
In an embodiment, a charge pump of relatively simple design is provided which can generate sufficient drive voltage for a power switching device from a low-supply-voltage (e.g., 1V). In some embodiments, this charge pump performs better at lower input voltages when there are loading conditions (i.e., when the charge-pump output powers other circuit blocks such as amplifiers and LDO's).
