Abstract

The invention relates to a data pipeline comprising a first stage with a data input for receiving a digital data input signal, a clock input and a data output, and a first bi-stable element being adapted to be switched in response to an edge of a first clock signal, and a dynamic latch stage comprising an input transfer element, and a second bi-stable element coupled between the input transfer element and a dynamic latch data output, wherein the input transfer element is adapted to be switched by a second clock signal and a delayed second clock signal, which is delayed with respect to the second clock signal by a first period of time being shorter than half a period of the second clock signal, such that the input transfer element allows signal transfer only during the first period of time.
