Duty ratio correction circuit and duty ratio correction method

A duty ratio correction circuit includes a clock input buffer that receives a first clock signal, a clock duty adjuster that adjusts a duty ratio of a second clock signal output from the clock input buffer based on a correction signal and generates a third clock signal, a data input buffer that rece...

Zusammenfassung:	A duty ratio correction circuit includes a clock input buffer that receives a first clock signal, a clock duty adjuster that adjusts a duty ratio of a second clock signal output from the clock input buffer based on a correction signal and generates a third clock signal, a data input buffer that receives a first data signal, a data duty adjuster that adjusts a duty ratio of a second data signal output from the data input buffer based on the correction signal and generates a third data signal, and a duty comparator that generates the correction signal based on the third clock signal.
