Patent abstract
A charge pump generates a first sub up current and a second sub up current that vary complementarily with a change in a voltage at an output terminal. The charge pump also generates a first sub down current and a second sub down current that vary complementarily with the change in the voltage at the output terminal. With such complementary relationships, the total up/down currents remain substantially constant and balanced with the change in the voltage at the output terminal.
