A switching circuit includes a plurality of switching elements connected between an input node and an output node and each comprising a first and second electrode connected to the input node and output node, respectively. The switching elements include a control electrode for controlling electrical conductance between the first and second electrodes such the switching element can be switched between an ON conductance state and an OFF conductance state. A detection circuit in the switching circuit outputs a detection value corresponding to an output current at the output node. A control circuit changes the conductance state of at least one switching element such that the summed total of the parasitic capacitances of all switching elements in the ON state decreases as the output current decreases as indicated by the detection value. |
