Abstract:
Memories, multi-phase clock signal generators, and methods for generating multi-phase duty cycle corrected clock signals are disclosed. For example, one such clock signal generator includes a delay-locked loop having a first multi-tap adjustable delay line configured to delay a reference signal to provide a plurality of clock signals having different phases relative to the reference clock signal. A periodic signal generated by the delay-locked loop is provided to a second multi-tap adjustable delay line as an input clock signal. Clock signals from taps of the second multi-tap adjustable delay line are provided as the multi-phase duty cycle corrected clock signals.
