Patent ID: 7456720

Claim:
A microelectronic device, comprising: a coupled inductor structure including: a first inductor on a first metallization layer of a microelectronic die; and a second inductor, that is inductively coupled to said first inductor, on a second metallization layer of said microelectronic die, said second inductor having a first inductor portion having a first plurality of parallel strips, a second inductor portion having a second plurality of parallel strips, and a bend portion to conductively couple said first inductor portion to said second inductor portion, said bend portion including: a single strip forming a 90 degree bend, said single strip having a first end and a second end; a first conductive block having a first edge and a second edge, said first edge being connected to said first end of said single strip and said second edge being connected to an end of said first plurality of parallel strips, wherein said second edge is substantially perpendicular to said parallel strips in said first plurality of parallel strips; and a second conductive block having a third edge and a fourth edge, said third edge being connected to said second end of said single strip and said fourth edge being connected to an end of said second plurality of parallel strips, wherein said fourth edge is substantially perpendicular to said parallel strips in said second plurality of parallel strips; wherein said strips in said first plurality of parallel strips have substantially the same length as one another and said strips in said second plurality of parallel strips have substantially the same length as one another.
