HIGHLY COUPLED INDUCTOR DESIGN FOR REDUCING AREA AND POWER

Circuits, integrated circuits, and radar systems are provided that implement highly coupled inductor designs for multi-core oscillators. An example circuit may include a plurality of inductors, each inductor including a first inductor portion and a second inductor portion electrically connected in series. In some embodiments, for each inductor, the first inductor portion may be magnetically coupled to a first inductor portion or a second inductor portion of a first coupled inductor of the plurality of inductors, and the second inductor portion may be magnetically coupled to the first inductor portion or the second inductor portion of a second coupled inductor of the plurality of inductors, wherein the first coupled inductor and the second coupled inductor are different inductors. 提供了针对多核振荡器实现高度耦合的电感器设计的电路、集成电路和雷达系统。示例电路可以包括多个电感器，每个电感器包括：串联电连接的第一电感器部分和第二电感器部分。在一些实施例中，针对每个电感器，第一电感器部分可以被磁耦合到多个电感器的第一耦合电感器的第一电感器部分或第二电感器部分，并且第二电感器部分可以被磁耦合到多个电感器的第二耦合电感器的第一电感器部分或第二电感器部分，其中第一耦合电感器和第二耦合电感器是不同的电感器。
