ABSTRACT:
A delay device has series-connected multiplexers in a differential form. First connections of the multiplexers are connected to the output of an upstream multiplexer. Second inputs of the multiplexers are connected to the input connection to which the signal to be delayed can be supplied. A control signal controls the switch setting of one of the multiplexers such that its output is connected to the input of the delay device. The other multiplexers have the other switch setting. In consequence, a specific delay time is set for the delay device. The multiplexers have four current paths which are coupled in pairs. One of the current path pairs can be decoupled from the current source via a transistor.
