Paper Abstract

This paper presents the application of APD photoelectrical transformation components to the technology of photomagnetical memory system. An expression for the signal-to-noise ratio has been derived by the mathematical method. This theoretical expression points out the path to improve the signal-to-noise ratio and also provides the technical requirements for selecting the components. This paper analyzes the important parameters of the APD pre-amplifier of photoelectrical signal and the measurement of equivalent input noise Eni, at the last gives the test results of the pre-amplifier.
