Autoregressive Modeling Of Dispersive Microstrip Tansmission Lines

Microwave and high-speed VLSI integrated circuits are lirnited by the propagation characteristics of the on-chip in- terconnections. Pulse dispersion on microstrip transmission lines is simulated using an equivalent lumped-distributed circuit. Transient analysis circuit simulations are performed to generate a synthetic time domain response. The impulse response of the simulated microstrip line is determined and modeled by an autoregressive lattice filter. The microstrip measurement technique will use photoconductors with picosecond pulsing and sampling speeds. The photo- conductors are excited by a pulsed laser and picosecond time domain measurements are obtained along the microstrip. Computer simulation results are compared with available measurement data to evaluate the performance of the model.
