Inductor structure and application thereof

摘要

The present disclosure relates to composite inductor structures for use in integrated circuits. There is provided a composite inductor structure comprising a first inductor coil and a second inductor coil. The second inductor coil comprises a multi-turn loop that surrounds the first inductor coil. The first inductor coil comprises two multi-turn loops which are connected in a figure-of-eight configuration about a central terminal so as to cause a current flowing in a first loop of the multi-turn loops to circulate around the first loop in a first rotational direction, and a current flowing in a second loop of the multi-turn loops to circulate around the second loop in a second rotational direction opposite the rotational direction of current flow in the first loop, said direction of current flow in the first and second loops being mirror images of each other.

主权项

1. A five-terminal passive device for use in integrated circuits, the device comprising:
a first inductor coil comprising
a first loop connected to a first terminal and a central terminal, anda second loop connected to a second terminal and the central terminal,wherein the first loop and the second loop are configured in a figure-of-eight so that a current flowing in the first inductor coil circulates around the first loop in a first rotational direction and circulates around the second loop in a second rotational direction opposite the first rotational direction; and a second inductor coil comprising a loop that surrounds the first inductor coil, wherein a first end of the second inductor coil connects to a third terminal,
a second end of the second inductor coil connects to a fourth terminal, anda midpoint of the second inductor coil connects to the central terminal.
