Patent ID: 8866541

Claim:
An integrated circuit comprising: a main path, comprising a first analog circuit having an input impedance, the main path having a first output, wherein the input impedance generates a first non-linear current; a cancellation path, sharing a common input with the main path, comprising a second analog circuit having a cancellation impedance, the cancellation path having a second output different from the first output, wherein the cancellation impedance generates a second non-linear current; an input network providing a common input voltage to drive the main path and the cancellation path of the integrated circuit; and a source impedance representing an impedance of the input network driving the main path and the cancellation path of the integrated circuit; wherein the cancellation path is parallel to and separate from the main path, wherein the second non-linear current, drawn to the cancellation impedance, substantially cancels the first non-linear current drawn to the input impedance, resulting in a decrease of a non-linear source current flowing through the source impedance.
