Abstract:
1. A differential inductor comprising: a first conductive path lying in a first plane having a first portion coupled to a first port and a second portion coupled to a second port; a second conductive path lying in a second plane spaced apart from the first plane, having a first portion, a second portion, and a third portion; and a third conductive path and a fourth conductive path each lying in a third plane spaced apart from the first plane and second plane; said first portion of said first conductive path configured to receive a signal through the first port and couple the signal to the first portion of said second conductive path on said second plane, said first portion of said second conductive path configured to couple the signal to the third conductive path on said third plane, said third conductive path configured to couple the signal to said second portion of said second conductive path on said second plane, said second portion of said second conductive path configured to couple the signal to said fourth conductive path on said third plane, said fourth conductive path configured to couple the signal to the third portion of said second conductive path on said second plane, and said third portion of said second conductive path configured to couple the signal to the second portion of said first conductive path.
