摘要： A memory controller for receiving a differential data strobe signal and an application processor having the memory controller are disclosed. The memory controller includes a strobe signal receiver configured to receive first and second strobe signals from a memory device as differential data strobe signal and output a first detection signal based on a level of each of the first and second strobe signals, a comparator configured to receive the second strobe signal and a reference voltage and compare a level of the second strobe signal with a level of the reference voltage to output a second detection signal, and a gate signal generator configured to generate a gate signal masking a portion of a period corresponding to the differential data strobe signal using the first detection signal and the second detection signal.

摘要： An X-ray apparatus includes an X-ray source configured to radiate X-rays, a collimator configured to adjust a radiation field of the X-rays and rotate on an optical axis direction of the X-rays, a ring-shaped first rotation transfer unit centered on an optical axis of the X-rays in the X-ray source, a second rotation transfer unit interlocked with the ring-shaped first rotation transfer unit and configured to rotate as the collimator rotates, a rotation sensor configured to sense an amount of rotation of the second rotation transfer unit, and a detector comprising a receiving surface on which the X-rays radiated from the collimator are incident.
