A common file format for storing the lookup tables is the Liberty [2] [3] format. A very simple model called the K-factor model is sometimes used. This approximates the delay as a constant plus k times the load capacitance. A more complex model called Delay Calculation Language, [4] or DCL, calls a user-defined program whenever a delay value is ...
The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.
End-of-life, no longer updated; historically important, because many analog simulators are based on this project Xyce [17] Sandia National Laboratories: 2023 Windows, macOS, Linux * * Backend simulator, supports parallel simulation on Linux and macOS, can solve huge circuits
Electronic analog PID control loops were often found within more complex electronic systems, for example, the head positioning of a disk drive, the power conditioning of a power supply, or even the movement-detection circuit of a modern seismometer.
Static timing analysis (STA) is a simulation method of computing the expected timing of a synchronous digital circuit without requiring a simulation of the full circuit. High-performance integrated circuits have traditionally been characterized by the clock frequency at which they operate. Measuring the ability of a circuit to operate at the ...
The first example gives the circuit for a 6th order maximally flat delay. Circuit values for z a and z b for a normalized lattice (with z b the dual of z a) were given earlier. However, in this example the alternative version of z b is used, so that an unbalanced alternative can be easily produced. The circuit is
In general a digital delay-line based TDC, [19] also known as tapped delay line, contains a chain of cells (e.g. using D-latches in the figure) with well defined delay times . The start signal propagates through this chain and is successively delayed by each cell.
A series of resistor–capacitor circuits (RC circuits) can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay time of an analog delay line may be only a few nanoseconds or several milliseconds, limited by the practical size of the physical medium used to delay the signal and the propagation speed ...
