Abstract :
We describe those factors which influence the design of highspeed optical preamplifiers, and examine the exchange between bandwidth and noise in a shunt-feedback first stage. For a given preamplifier bandwidth, it is shown that an operating point exists which minimises the amplifier noise level.
