Abstract
A delay line, in accordance with the invention, includes a plurality of delay elements connecting an input and an output, the delay elements for causing a delay to be introduced to a signal passing through the delay elements. A voltage device is included for regulating power to the plurality of delay elements, the voltage device being adjustable to provide at least one predetermined voltage to the delay elements such that the delay in the delay elements is modified according to the predetermined voltage(s). The delay line may be employed in a delay locked loop, a clock circuit or other circuits.
