Abstract
The system described herein provides a minimized skew generator that has very small timing variation. Four phase signals are compressed into one signal including the four phase information. Therefore, the signal with all of the phase information travels on the same line, thus avoiding the concerns of skewing based on different sizes of metal lines. Since there are two rising edges and two falling edges within one signal, an enable line is utilized to select between the first and second, rising and falling edges. With this processing, the system has only one critical signal output, thus requiring only one signal line. Skewing of the signals and the amount of power required are both reduced.
