Abstract
In varying embodiments, the present inventive concepts relate to a notch filter for quadrature and differential signaling. No inductor is used in this notch filter, thus the integrated circuits silicon die area is small. In addition, the linearity of the notch filter is excellent because of the linearity of the resistors and capacitors in integrated circuits.
