1. An apparatus comprising:
a plurality of pull-up switches connected in parallel between a first voltage bus and a gate of a power switch, wherein the plurality of pull-up switches is configured such that in a turn-on process of the power switch, a gate current of the power switch changes twice so that a low turn-on gate current flows into the gate of the power switch after a first high turn-on gate current and before a second high turn-on gate current; and
a plurality of pull-down switches connected in parallel between the gate of the power switch and a second voltage bus, wherein the plurality of pull-down switches is configured such that in a turn-off process of the power switch, the gate current of the power switch changes twice so that a low turn-off gate current flows out of the gate of the power switch after a first high turn-off gate current and before a second high turn-off gate current.
