APPLICATION NOTE
Filter Models Implemented with ABM
By Bashir Al-Hashimi, PhD, School of Engineering, Staffordshire University, Stafford, ST180AD England
Analog behavior modeling (ABM) allows the simulation of analog circuits using mathematical equations. This
application note shows how the filter behavioral models are developed and implemented using the Laplace
function of PSpice, Given the filter bandwidth and order, the models simulate lowpass, highpass, bandpass, and
band-reject filters. For ease of use, the models are developed as parameterized sub-circuits. Simulation
examples are included to demonstrate the use of these models.
