  • Distortion cancellation in analog circuits
    Patent number: 8866541
    Abstract: Embodiments of the present invention may provide an improved apparatus and method for reducing distortion in analog circuits. A circuit in accordance with the present invention may include a main path comprising an analog circuit with an input impedance, a source impedance representing the impedance of an input network driving the analog circuit, and a cancellation path. The cancellation path may be in parallel to the main path and may generate a cancelling non-linear current to substantially cancel a non-linear current drawn to the input impedance, resulting in a decrease of non-liner current flowing through the source impedance.
    Type: Grant
