Abstract

Apparatus and methods for equalization are provided. In certain implementations, an equalizer includes first and second feedback resistors, first and second equalization resistors, an equalization capacitor, and an amplification circuit that includes first to fourth input terminals and first and second output terminals. The amplification circuit can receive a differential input voltage signal between the first and third input terminals, and the first and second equalization resistors and the equalization capacitor are electrically connected in series between the second and fourth input terminals with the equalization capacitor between the first and second equalization resistors. Additionally, the first feedback resistor is electrically connected between the first output terminal and the second input terminal, and the second feedback resistor is electrically connected between the second output terminal and the fourth input terminal.
