A distributed optical receiver preamplifier with unequal gate/drain impedances

Abstract

A near dc to 16.4 GHz wide band distributed amplifier, constructed using a 20 GHz MMIC GaAs process and optimised to operate as an optical receiver front end preamplifier, has been designed, realised and tested at 10 Gbit/s. The design uses a 75 /spl Omega/ gate line impedance to maximise the overall transimpedance gain without introducing severe bandwidth restriction.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
