ABSTRACT:
A data extracting circuit extracts data much more accurately at a much higher response speed. A clock transfer section propagates an input clock signal through unit delay devices thereof. An edge detecting section locates an edge of the clock signal, which edge is being propagated through the clock transfer section, for a time represented by a given edge of an input data signal. In response to an edge detection signal indicating the clock signal edge located, a clock selecting section selects one of outputs of the delay devices, and presents the output as a clock input to a latch.
