Abstract

According to some embodiments, a charge pump includes a first transistor to steer an amount of current to a second transistor coupled to the first transistor in a first folded cascode arrangement and to a current mirror to sink substantially the amount of current from a load, and a third transistor to steer the amount of current to a fourth transistor coupled to the third transistor in a second folded cascode arrangement to source substantially the amount of current to the load.
