摘要: A duty cycle measurement circuit and method of operation is described that is particularly well adapted for use in microelectronics devices. In one embodiment, the circuit the includes a clock signal selector to alternately select the high or the low phase of an input clock signal, a sweep circuit to sweep a timing parameter through a range, and a latch to compare the clock signal to the timing parameter and generate a result.

摘要: Described herein are apparatus, method, and system for re-synthesizing a clock signal. The apparatus comprises: a first logic unit to detect a rising edge of an input clock signal and for generating a rising edge of an output clock signal based on the detected rising edge of the input clock signal, the input clock signal having a non-50% duty cycle and a first period; and a second logic unit to compute a falling edge of the output clock signal according to the detected rising edge of the input clock signal, the falling edge of the output clock signal being near half of the first period.
