Abstract:
A clock buffer includes a reference enable signal generator configured to generate a reference enable signal enabled in synchronization with a rising edge of a first period of a second clock after a clock enable signal is enabled, a delay enable signal generator configured to generate a delayed enable signal enabled in synchronization with a rising edge of a second period of a first clock after the reference enable signal is enabled, a first output unit configured to receive the reference enable signal and the first clock to generate a first internal clock, and a second output unit configured to receive the delayed enable signal and the second clock to generate a second internal clock.
