Crosstalk between signal lines is unavoidable in signal lines system of sensor. Crosstalk seriously affect the integrity of signal lines system. A method for reducing crosstalk between signal lines is proposed

aiming at signal lines system of sensor

a new guard line reduce crosstalk based on inverter

the physical structure of this guard line is very simple

thus using this kind of guard line can reduce the cost of design. Simulation circuits are built to verify the correctness of this method

and the result show that signal line without inverter guard line is serious affected by crosstalk and the signal on signal line occur error code

the crosstalk on signal line adding inverter guard line is significantly reduced and the goodness of fit is 100 % comparing with original signal

thus it proves that inverter guard line has a strong ability to reduce crosstalk between signal lines of sensor.
