Helical Stacked Integrated Transformer and Inductor

摘要

A helical stacked integrated transformer formed by a first inductor and a second inductor includes a first helical coil that has a first outer coil and a first inner coil, a second helical coil that shares an overlapped region with the first helical coil and has a second outer coil and a second inner coil, and a connection structure that connects the first helical coil and the second helical coil. The first inner coil is located inside the first outer coil and the second inner coil is located inside the second outer coil. The first inductor includes a part of the first helical coil and a part of the second helical coil. The second inductor includes a part of the first helical coil and a part of the second helical coil.
