A latching element latches incoming data into an integrated circuit. The latching element (for example, a latch or flip-flop) can be considered to include a data path portion, a clock path portion, and an ideal latching element. In one embodiment, an open-loop replica of the data path portion is disposed in a clock signal path between a clock input terminal of the integrated circuit and a clock input lead of the latching element. In a second embodiment, an additional replica of the clock path portion is disposed in a data signal path between a data terminal of the integrated circuit and a data input lead of the latching element. The replica circuits help prevent changes in skew between a data path propagation time to the ideal latching element and clock path propagation time to the ideal latching element. Setup times remain substantially constant over PVT (process, supply voltage, temperature).
