  • CMOS clock receiver with feedback loop error corrections
    Patent number: 8004331
    Abstract: A system for correcting duty cycle errors in a clock receiver that includes a differential amplifier having inputs for a pair of differential clock signals. A duty cycle error detector has inputs for a pair of amplified clock signals and an output for a duty cycle error correction signal. A signal conditioner is also provided with the differential amplifier having an input for the duty cycle error correction signal. Furthermore, the signal conditioner adjusts the differential clock signals in response to the duty cycle error correction signal. Also, a system for correcting cross point errors in a clock receiver that includes a differential amplifier having inputs for a pair of differential clock signal. A cross point error detector has inputs for a pair of amplified clock signals and an output for a cross point error correction signal. A signal conditioner is also provided with the differential amplifier having an input for the cross point error correction signal.
