Abstract
A passive equalizer is provided. The passive equalizer includes a first resistive element, a first inductive element, a second resistive element, and a first variable capacitor. The first resistive element is coupled between an input node and an output node. The first inductive element and the second resistive element are coupled in series between the output node and a first voltage supply node. The first variable capacitor is coupled between the input node and a first node located between the first inductive element and the second resistive element.
