Equalizer circuitry including both inductor based and non-inductor based equalizer stages

摘要

An equalizer circuitry that includes both inductor based and non-inductor based equalizer stages is provided. In one implementation, the equalizer circuitry includes a first equalizer circuitry including a first inductor based equalizer stage and a first non-inductor based equalizer stage coupled to the first inductor based equalizer stage. In one implementation, the equalizer circuitry further includes a second equalizer circuitry including a plurality of inductor based equalizer stages, where the plurality of inductor based equalizer stages includes the first inductor based equalizer stage. In one implementation, the first equalizer circuitry further includes a second inductor based equalizer stage coupled to the first inductor based equalizer stage and the first non-inductor based equalize stage.
