Abstract
Circuits for adjusting the duty cycle of a clock(s) signal include a negative feedback loop for applying an offset signal to the uncorrected clock signal(s). The offset signal, which corresponds to a duty cycle error of the corrected clock signal(s), adjusts the slicing level of the uncorrected clock signal(s) to cause the duty cycle error to converge toward a predetermined value, for example, zero. The techniques may be used to adjust the duty cycle error of differential clock signals as well as single-ended clock signals.
