摘要： A power switch of a processing device comprises a plurality of series-connected switching stages, with each switching stage comprising a plurality of parallel-connected switching devices and an inverter chain. The switching devices are coupled between a power supply input and a power supply output of the power switch. Each of the switching devices of a given one of the switching stages is driven by an output of a corresponding one of the inverters of the inverter chain of that stage. A control input of the first switching stage receives a control signal for controlling a state of the power switch, and a control input of each remaining switching stage is driven by a control output of an immediately preceding switching stage. The switching devices in one or more of the switching stages are configured to have different switching characteristics than the switching devices in at least one other stage.
