低共模耦合效应的集成电路制造技术

一种集成电路，其形成于同一个晶片内，其包括：工作于第一频率的第一电路，其包括第一电感；包括第二电感的第二电路，其对输入信号进行处理，该输入信号的偶次谐波的频率位于所述第一频率附近，该第二电感包括第一连接端(A)、第二连接端(B)、中间连接端(M)、中间节点(D)、连接于第一连接端(A)和中间节点(D)之间的第一线路、连接于中间节点(D)和第二连接端(B)之间的第二线路以及连接于中间节点(D)和中间连接端(M)之间的中间抽头，第一线路和第二线路延伸形成一匝或多匝线圈。在电流从第一连接端(A)流向中间连接端(M)，从第二连接端(B)流向中间连接端(M)时，第一线路、第二线路和中间抽头上的电流产生的磁场能够基本互相抵消，从而降低了第二电路对第一电路的共模耦合的影响。

Integrated circuit with low common mode coupling effect

An integrated circuit, which is formed in the same chip, which includes the first circuit working at the first frequency, including the first inductor, including a second circuit of the second inductor, which processes the input signal, and the frequency of the dual harmonics of the input signal is located near the first frequency, and the second inductor includes the first. The connection end (A), the second connection end (B), the intermediate connection end (M), the intermediate node (D), the first line connected to the first connection end (A) and the intermediate node (D), the second line connected between the intermediate node (D) and the second connection end (B), and the intermediate tap connected between the intermediate node (D) and the intermediate connection end (M), the first line And second lines extend to form one turn or multi turn coils. When the current flows from the first junction (A) to the intermediate junction (M), from the second connection end (B) to the intermediate connection end (M), the magnetic field generated by the current on the first line, the second line and the intermediate tap can basically counteract each other, thereby reducing the effect of the second circuit on the common mode coupling of the first circuit.
