An analytical method for finding the maximum crosstalk in lossless-coupled transmission lines

The crosstalk in a system containing n(n>or=2) lossless microstrip transmission lines is formulated as a linear function in time. The maximum crosstalk is computed by evaluating the crosstalk at certain breakpoints in time. The technique also provides the pattern (rising or falling) of input voltages and their relative delays for which the maximum crosstalk occurs. This pattern is usually determined by the system parameters. Since the maximum crosstalk determines the faulty vs fault-free operation, the pattern found could be used for testing integrated logic circuits during the design stage.<>
