HIGHLY COUPLED INDUCTOR DESIGN FOR REDUCING AREA AND POWER CONSUMPTION OF A MULTI-CORE OSCILLATOR

HIGHLY COUPLED INDUCTOR DESIGN FOR REDUCING AREA AND POWER CONSUMPTION OF A MULTI-CORE OSCILLATOR

A circuit (200), integrated circuit (600, 900), and radar system (1000) implementing a highly coupled inductor design for a multi-core oscillator is provided. An example circuit may include a plurality of inductors, each inductor including: a first inductor portion (120, 124, 220, 224) and a second...

Zusammenfassung:A circuit (200), integrated circuit (600, 900), and radar system (1000) implementing a highly coupled inductor design for a multi-core oscillator is provided. An example circuit may include a plurality of inductors, each inductor including: a first inductor portion (120, 124, 220, 224) and a second inductor portion (122, 126, 222, 226) electrically connected in series. In some embodiments, for each inductor, the first inductor portion (120) may be magnetically coupled (k120,226) to a first or second inductor portion (226) of a first coupling inductor of the plurality of inductors, and the second inductor portion (122) may be magnetically coupled (k122,220) to a first or second inductor portion (220) of a second coupling inductor of the plurality of inductors, where the first coupling inductor and the second coupling inductor are different inductors.
