Methods, circuits, devices, and systems are provided, including a delay line for a delay-locked loop. One method includes providing a reference clock to a first delay unit in a delay line. The delay line includes a number of delay units coupled together. Even delay units, among the delay units, are coupled to an even clock line to generate a first intermediate clock. Odd delay units are coupled to an odd clock line to generate a second intermediate clock. The even and odd delay units are configured to in a manner intended to restrict an increase in drive to load ratio and to intrinsic delay as additional delay units are coupled to the number of delay units.
