Abstract:
1. A circuit arrangement for producing a dual-rail output signal comprising: a first input with at least two connections for receiving a dual-rail input signal; a second input for receiving a control signal; a signal processing apparatus having a first switch and a second switch, which are each driven as a function of the input signal, and having two outputs, wherein the first output of the signal processing apparatus is connected via one of the switches to a foot point, which is at a first potential, of the signal processing apparatus, and the second output of the signal processing apparatus is connected via the other switch to the foot; a switching apparatus, having two inputs, which are connected to the respective outputs of the signal processing apparatus, and two outputs which are connected to two respective outputs of the circuit arrangement in order to output a dual-rail output signal, wherein the outputs of the switching apparatus are each connected to one or both of the inputs of the switching apparatus as a function of the control signal; and a potential monitoring apparatus for defining the potentials at the outputs of the circuit arrangement when the outputs of the circuit arrangement are not connected via the switching apparatus and the signal processing apparatus to the foot of the signal processing apparatus.
