Phase error cancellation for differential signals

Abstract

In one embodiment, the present invention includes an electronic circuit comprising a first stage having a first differential inductive element and a second differential inductive element, and a second stage coupled to an output of the first stage, the second stage having a first differential inductive element and a second differential inductive element, wherein the first and second differential inductive elements of the first stage couple magnetically to generate a first phase error, wherein the first and second differential inductive elements of the second stage couple magnetically to generate a second phase error, and wherein the second phase error cancels the first phase error.
