Transfer functions of on-chip global interconnects based on distributed RLCG interconnects model

Novel transfer functions for on-chip global interconnects are rigorously derived based on distributed resistance, inductance, capacitance and conductance (RLCG) transmission line model with typical boundary conditions. The new interconnect transfer function reveals that the distributed conductance of interconnects has a severe effect on interconnect performance. The peak value of voltage decreases about 50% in the case of g=0.33 S/m, compared with the ideal lossless case of g=0 for the finite length interconnect with an open circuit termination and an arbitrary source impedance. The crosstalk between coupled interconnects is also examined and demonstrated numerically.
