带环形铁氧体磁芯的高电感键合线微型变压器的建模、设计与制造

This paper presents the design of miniaturized bond wire transformers assembled with standard IC bonding wires and NiZn and MnZn ferrite toroidal cores. Several prototypes are fabricated on a printed circuit board substrate with various layouts in a $4.95\; {\rm mm} \times 4.95\; {\rm mm}$ area. The devices are modeled by analytical means and characterized with impedance measurements over a wide f...
