摘要： An integrated circuit includes a chain of delay elements, a first phase detector, and a controller. The chain of delay elements is configured to delay an input clock signal for providing an output clock signal phase shifted with respect to the input clock signal by a selected value. The first phase detector is configured to provide a common control signal to each delay element based on a phase difference between the input clock signal and a signal output from one of the delay elements to adjust a delay of each delay element. The controller is configured to provide an independent control signal to each delay element to individually adjust the delay of each delay element such that the delay of each delay element is equal.

摘要： A calibration apparatus is provided for adjusting the relative phase between two signals received at a memory chip, the two signals being generated such that they are synchronized with one another in a controller and are transmitted to the memory chip via separate lines. The calibration apparatus comprises a measuring device, which is arranged in the memory chip and is designed for measuring the relative phase between the two received signals, and a feedback loop containing a phase-controlling correction device. The measuring device is designed for generating an item of control information indicating the deviation of the measured relative phase from a defined tolerance range. The correction device responds to the control information to compensate for the deviation. The correction device is arranged in the controller and is designed for influencing the relative phase between the two signals to be transmitted to the memory chip. The feedback loop contains a signal connection leading from the memory chip to the controller.
