  • Patent number: 6348826
    Abstract: A variable-delay circuit on an integrated circuit is used to delay a periodic strobe signal. In normal operation, the strobe signal can be shifted 90 degrees to center it within a data bit cell. In test mode, it can also be shifted up to 270 degrees in N increments to measure the effective input latch setup and hold timings. The variable-delay circuit comprises a voltage-mixing interpolator circuit to produce phase delays in N increments. The variable-delay circuit can incorporate an existing delay locked loop. Also described are an electronic system, a data processing system, and various methods of performing on-chip testing and calibration.
