A switching arrangement for a circuit, the switching arrangement comprising: a signal input (Vin,1); a signal output (Vout); a switching stage (30) that has a control input, the switching stage being operative, in response to a control signal applied to the control input changing between a first voltage level and a second voltage level, to change between a first state in which it causes a signal on the signal input to pass to the signal output and a second state in which the signal output is muted; and a control stage (24) that operates: in a steady mode to apply a steady signal to the control input of the switching stage at one or other of the first or the second voltage level to cause the switching arrangement to be maintained in its first or its second state as required; and in a switching mode to apply a switching signal that transitions between the first voltage level and the second voltage level to the control input of the switching stage to cause the switching arrangement to transition between its first and its second state. |
