5.6 mm x 5.6 mm integrated toroidal inductors with reduced thickness down to 200 mu m have been realized. A high inductance-to-dc resistance ratio have been achieved using a toroidal geometry. The realization features thick Cu winding and a thick laminated Ni80Fe20 core with crossed anisotropy. Impedance measurements have been performed up to 100 MHz with dc bias current applied. As a typical result, we show an inductor with an inductance of 500 nH up to 10 MHz and a dc resistance of 95 m Omega. To the best of our knowledge, this is the highest inductance-to-dc-resistance ratio demonstrated by a fully integrated inductor. This demonstrates the interest of such integrated inductors to replace discrete components in compact low-power modules.
