Excess delay factor associated with dominant poles of trimmed distributed RC networks

A new technique for calculating the excess delay factor associated with the finite dominant pole approximation of the open-circuit voltage transfer function of trimmed uniform distributed RC networks is reported. This technique is based on Elmore´s definition of the delay time which is associated with the transient response of the system. This response is then used to calculate a number of dominant poles and their associated delay factors. These are used to obtain the frequency and phase response of the network which is then compared with that obtained from a steady-state analysis.
