Abstract: A system and method for measuring mutual inductance between adjacent first communication transmission line and second communication transmission line is disclosed. The system includes a mutual inductance measurement circuit that includes a coupling generator which biases the first communication transmission line with a current ramp signal; a sample and hold circuit which captures an induced voltage on the second communication transmission line using a switched capacitor storage element; a switched capacitor integrator configured to integrate the induced voltage onto an output voltage node; and a comparator configured to switch states once the switched capacitor integration has surpassed a reference trippoint.

Abstract: A system for measuring parasitic capacitance coupling between adjacent first communication transmission line and second communication transmission line is disclosed. The system including: a parasitic tolerant capacitive based coupling measurement circuit (CBCM), the CBCM including: a capacitive auto-zeroing buffer configured to bias the second communication transmission line and displace coupling charge transferred from the first communication transmission line to a switched capacitor storage element; a capacitive trans-impedance amplifier configured to integrate displaced coupling charge onto an output voltage node; and a comparator configured to switch states once the capacitive trans-impedance amplifier integration has surpassed a reference trippoint.

Abstract: A method for determining mutual coupling between adjacent communication transmission lines is disclosed. The method includes providing a first periodic signal to a first communication transmit end of a first communication transmission line; providing a second periodic signal to a second communication transmit end of a second communication transmission line, wherein the first communication transmission line is adjacent to the second communication transmission line; measuring a time of zero-crossing at a second communication receive end of the second communication transmission line compared with a zero-crossing of an ideal reference signal; and determining a mutual coupling level based on the time of zero-crossing on the second communication transmission line compared with a zero-crossing of an ideal reference signal that was measured.
