Abstract
ln wideband optical communications the bandwidth and the noise of
optical receivers are crucial problems. The application of a distributed
amplifier instead of a transimpedance amplifier in an optical receiver
has the advantage of high speed and low noise t1], p] The
characteristics of an optical receiver are not only determined by the
parameters of the photodiode (PD) and the distributed ampli{ier
driven by the diode, but they are also greatly influenced by the
matching circuit [3]. ln this paper the gain and the input equivalent
noise current of the amplifier are compared in diflerent matching
configurations. 0ne of the matching circuits has been experimentally
verified as well.
