Abstract
A duty cycle detector comprising a first circuit configured to receive clock cycles including a first level and a second level. The first circuit is configured to obtain a first value based on the length of the first level and to obtain second and third values based on the length of the second level. The first value is compared to the second and the third values to determine a duty cycle range of the clock cycles.
