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
From the measured data on the transmission line Zobel proposed the following attenuation values. At f 1 = 40 Hz, A 1 = 0.536 neper; at f 2 = 200 Hz, A 2 = 0.291 neper; at f 3 = 800 Hz, A 3 = 0.176 neper; at f 4 = 2000 Hz, A 4 = 0.100 neper. (These give a response which is the inverse of that of the original plot, as required for the equalizer ...
2.8 GHz superconducting bridged T delay equaliser in YBCO on lanthanum aluminate substrate. Losses in the circuit cause the maximum delay to be reduced, a problem that can be ameliorated with the use of high-temperature superconductors. Such a circuit has been realised as a lumped-element planar implementation in thin-film using microstrip ...
It is easily converted to an unbalanced bridged-T circuit, as shown on the right. When Z 1 Z 2 = R 0 2 it becomes a constant resistance network, which has an insertion loss given by () = + When normalized to 1ohm, the source, load and R 0 are all unity, so Z 1.Z 2 = 1, and the insertion loss becomes
Elmore delay [5] is a simple approximation, often used where speed of calculation is important but the delay through the wire itself cannot be ignored. It uses the R and C values of the wire segments in a simple calculation. The delay of each wire segment is the R of that segment times the downstream C. Then all delays are summed from the root.
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 of impulses in the medium. Analog delay lines are applied in many types of signal processing circuits; for example the PAL television standard uses ...
The problem with having a complicated circuit (i.e. one with many elements, such as logic gates) is that each element takes up physical space and costs time and money to produce. Circuit minimization may be one form of logic optimization used to reduce the area of complex logic in integrated circuits .
The method of logical effort, a term coined by Ivan Sutherland and Bob Sproull in 1991, is a straightforward technique used to estimate delay in a CMOS circuit. Used properly, it can aid in selection of gates for a given function (including the number of stages necessary) and sizing gates to achieve the minimum delay possible for a circuit.
