    • A method and system of frequency domain equalization. In an embodiment, the frequency domain equalizer system includes a transmit driver. A receiver decision circuit is communicatively coupled to the transmit driver. The receiver decision circuit may have an input signal and an output signal. An all-pass filter may be communicatively coupled to the transmit driver and the receiver decision circuit. The all-pass filter having an all-pass input signal which comprises an integration of a summation of the receiver decision circuit input signal and the receiver decision circuit output signal, each signal being acted upon by at least one band-pass filter.

    • The present invention is an apparatus and system for providing a high quality spiral inductor in an integrated circuit environment. A layer of inductor may be placed within the metal layers along with negative capacitance generation circuitry of the present invention to compensate for the capacitance associated with the metal layers adjacent to the inductor to provide a higher quality factor for the inductor. Advantageously, circuitry of the present invention may be employed within an integrated circuit without modifying the layer structure of the integrated circuit. Additionally, values of the components of the circuitry may be selectively and independently chosen to synthesize a variable range of negative capacitance.
