Apparatus for long-reach, low-power active copper channels

Abstract

A redriver circuit, apparatus, and method for long-reach, low-power active copper channels. The redriver includes an input block configured to receive signals and a low-frequency attenuator coupled to the input block. The low-frequency attenuator is configured to attenuate low-frequency components of the signals. The redriver includes a low noise front end amplifier coupled to the low-frequency attenuator and configured to provide low-noise amplification to the attenuated low-frequency signals and maintain a target input impedance. The redriver includes an amplifier stage coupled to the low noise front end amplifier and configured to amplify output signals from the low noise front end amplifier. The amplifier stage is configured to provide the amplified output signals.
