PVT Method and apparatus for high speed delay for real-time PVTProcess Voltage Temperature compensation using delay line

摘要

A fast delay method and apparatus for real-time PVT correction using a delay line are disclosed. Delay unit for performing a fast delay for real-time PVT (Process, Voltage, Temperature) correction includes a plurality of delay lines for adjusting the delay skew of the input signal and a delay line controller for control of the plurality of delay lines Each of the plurality of delay lines may include a data delay line and a reference clock delay line, and the data delay line receives and delays data, and the reference clock delay line receives and receives a reference clock as an input or a data delay line. Correction control information for correction of a delay value may be provided.
