We propose two-pole one-zero second-order approximations for transfer functions in resistance-inductance-capacitance trees. The approximation matches the first three moments of the original transfer function. Formulas for computing step-response parameters such as delay time, rise time, overshoot, etc., are given. Simulation results show that adding the zero improves accuracy of the approximation.
