Integrated circuits with delay circuitry are provided. Delay circuitry may receive a clock signal and generate a corresponding delayed clock signal. The delayed clock signal generated using the delay circuitry may exhibit reduced duty cycle distortion in comparison to conventional systems. The delay circuitry may include a pulse generation circuit, a delay circuit, and a latching circuit. The pulse generation circuit may generate pulses in response to detecting rising edges or falling edges at its input. The pulses may propagate through the delay circuit. The latching circuit may generate (reconstruct) a delayed version of the clock signal in response to receiving the pulses at its control input. The delay circuitry may be used in duty cycle distortion correction circuitry, delay-locked loops, and other control circuitry. |
