PURPOSE:To reduce the leakage of jamming signals by a method wherein, in an integrated circuit, an interconnection with polarity signals reverse to that of a jamming interconnection is provided on the jamming interconnection to transmit polarity signals reverse to that of jamming interconnection to a jammed interconnection. CONSTITUTION:A substrate 11 is provided with a long and large-spaced jammed interconnection 3 connected to an input terminal of an amplifier 2. A compensating interconnection 21 receiving polarity signals reverse to that of a jamming signal source 4 from a polarity reversing circuit 20 is arranged close to a jamming interconnection 15 connected to the jamming signal source 4. The leakage of jamming signals is proportional to the difference between the coupling capacity value between the interconnections 3 and 15 and the other coupling capacity value between the interconnection 3 and 21. In such a constitution, the jamming interconnection 15 and the compensating interconnection 21 are closely interconnected to make the distance (d) between them shorter than the distance (D) between the jamming interconnection 15 and the jammed interconnection 3. Resultantly, the interconnections 15, 21 can take almost the same shape to reduce the leakage of jamming signals.
