Abstract
Abstract A signal transmission circuit includes an input pad (IT) for receiving an input signal, a resistor (R) connected at one end to the input pad, and a signal transmission line (TL) connected at the input end to the other end of the resistor (R), and at the output end to an internal circuit (10). The signal transmission circuit further includes an auxiliary line (AL) connected at the input end to the input pad (IT), floating electrically at the output end, and extending substantially in parallel with the transmission line (TL).
