摘要:
Duty cycle correction devices for static compensation of an active clock edge shift. A duty cycle correction circuit in the duty cycle correction device corrects a clock input signal, according to a first control signal. A programmable delay circuit or a modified duty cycle correction circuit in the duty cycle correction device compensates a shift of an active clock edge in a clock output signal of the duty cycle correction circuit, according to a second control signal. A mapping circuit in the duty cycle correction device generates the second control signal by mapping a digital value of the first control signal and a digital value of the second control signal.
