A wide bandwidth sige broadband amplifier for 100 Gb/s Ethernet applications

Abstract

We present a low-voltage, low-power SiGe broadband amplifier with a bandwidth of 62 GHz, which is intended for use in 100 Gb/s Ethernet applications. The amplifier consumes only 125 mW from a 2.5 V supply. To the authors' knowledge this is the lowest reported power for a non-distributed amplifier with more than 60 GHz bandwidth in a SiGe process technology.
