Abstract
A duty cycle corrector including a restore circuit configured to receive a differential input clock and a differential feedback clock each having crossings of a first type and a second type and to provide a differential output clock having crossing of the first type based on differential input clock crossings of the first type and crossings of the second type based on differential feedback clock crossings of the first type. A delay element configured to delay the differential output clock by a delay time to provide the differential feedback clock. An adjuster circuit configured to receive the differential input and feedback clocks and to adjust the delay time so as to maintain a duty cycle of the differential output clock substantially at a desired duty cycle.
