摘要： A switching stage is provided that generally includes multiple switching paths for routing a signal. For example, the switching stage may include a first switching path having at least one switching element for selectively connecting an input of the switching stage to an output of the switching stage and a second switching path having at least one switching element for selectively connecting the input of the switching stage to the output of the switching staged. In certain aspects, the first and second switching paths are controlled such that a signal is selectively routed from the input of the switching stage to the output of the switching stage via the first and second switching paths in dependence on the current of the signal to be routed.
