Abstract:
1. A digital signal delay device for converting a signal (IN) into a corresponding delayed signal (OUT), comprising a plurality of signal delay elements connected in series, wherein, as a function of the desired delay of the delayed signal (OUT), the respective output signal of a particular signal delay element is used for generating the delayed signal (OUT), wherein said signal delay elements each comprise one single inverter only, wherein said signal delay elements are respectively connected with corresponding gates, wherein as a function of the respectively desired delay, that gate is activated that is connected to the signal delay element whose output signal is to be used for generating the delayed signal (OUT), wherein when the output signal of the particular signal delay element is inverted vis-à-vis the signal (IN), the gate connected with the particular signal delay element is designed such that the gate advances the output signal in an inverted manner and, when the output signal of the particular signal delay element is non-inverted vis-à-vis the signal (IN), the gate connected with the particular signal delay element is designed such that the gate advances the output signal in a non-inverted manner.
