Systems and methods for suppressing rush current noise in a power switch cell

Abstract

A System and a method are disclosed for suppressing rush current noise in a power switch cell. The system comprises: a power switch (306) having an operational condition dependent upon the state of a control signal; and an inrush current limiter module (300) for outputting the control signal. The control signal transitions from a first value to an intermediate value and from the intermediate value to a second value, wherein the power switch is configured to operate in a low conductive (OFF) condition when the control signal has the first value, to operate in a high conductive (ON) condition when the control signal has the second value, and to operate in a moderately conductive condition when the control signal has the intermediate value. Therefore, when the power switch transitions from the OFF condition to the ON condition, the rush current noise may be reduced.
