A delay line is used to produce a number of digital signals, each one delayed in time with respect to each other. Delay lines serve a variety of functions within digital systems. Delay lines provide fixed delays and phase shifts that can perform a variety of signal processing functions. Delay lines are important components in many microwave and radio frequency (RF) circuits. Delay lines are frequently used to adjust timing inconsistencies at complex circuitry mounted to complex printed circuit boards that operate at ever increasing higher frequencies. Delay lines are used in digital circuits such as board level systems and integrated circuit (IC) devices, including field programmable gate arrays (FPGAs) and microprocessors, to control the timing of various signals in the digital circuits. Digital devices such as mobile phones, personal digital assistants (PDAs), and personal computers are utilized to conveniently handle digital information. When the digital device processes, exchanges, and distributes digital information, the digital device requires triggers generated from a clock signal to process digital data that are sequentially transmitted. A semiconductor integrated circuit accepts an external signal, and outputs an output signal after carrying out processing according to the input signal. Timing relative to an external input signal according to which an output signal is provided is therefore critical. To achieve changes in the delay, some delay lines add or subtract delay elements to achieve different delay times, or adjust the corresponding delay elements in a delay line chain to obtain the desired delay time. A delay line generally comprises a circuit device that imparts a fixed or sometimes variable delay to an input waveform. Delay lines generally consist of a set of smaller delay elements stacked one after another to form a longer delay line.
