Abstract

General considerations involved in designing wide bandwidth low-noise photodetector preamplifiers are discussed. A specific circuit configuration is presented which meets the general requirements for high-speed low-noise operation. Relevant noise equations are presented and theoretical results are compared to actual data for a working 50 MHz version of the preamplifier. Test data confirms the usefulness of this configuration.
