| Abstract: | This paper introduced a new kind of current steering charge pump whose current matching was achieved by two transistors in series. Furthermore, an accurate current copy circuit was used in the charge pump circuit to make the difference of the pull-up current and the pull-down current smaller. This design was proved by cadence simulating. |
