Abstract

Provided is a burst-mode receiver configured to receive an optical signal having a preamble and a data payload, the burst-mode receiver including a first bias resistor coupled between a first voltage supply and a photosensor, a first capacitor coupled between the photosensor and an amplifier, a first common-mode resistor configured to supply a voltage of a common-mode voltage supply to the amplifier, a first bypass switch configured to couple the first capacitor to the common-mode voltage supply while bypassing the first common-mode resistor, and a first data switch configured to couple the first capacitor to the amplifier, and to couple the first capacitor to the common-mode voltage supply through the first common-mode resistor.
