A tunable equalizer with a tunable equalizer frequency response is provided. The tunable equalizer includes an amplifier circuit for amplifying input signals and a tunable circuit coupled to the amplifier circuit. The tunable circuit is arranged to provide a zero point in the equalizer frequency response and the zero point is adjusted according to a controllable value. When the controllable value varies according to a uniform offset, the corresponding zero point varies according to a non-uniform offset.
