Abstract

A method includes tracking a tuning voltage at a first circuit coupled to a first drain node of a first supply of a charge pump. The method also includes tracking the tuning voltage at a second circuit coupled to a second drain node of a second supply of the charge pump. The method further includes stabilizing a first voltage of the first drain node and a second voltage of the second drain node responsive to the tuning voltage.
