Abstract
An equalizer, in at least some embodiments, comprises an amplifier configured to produce an amplified voltage signal that is a function of an ambient temperature affecting the equalizer. The equalizer also includes a linear equalizer stage coupled to the amplifier and comprising a transistor having a resistance controlled by the amplified voltage signal. The linear equalizer stage is configured to produce a voltage output signal having a gain that is dependent on the transistor resistance and on a frequency of the amplified voltage signal.
