RANDOM NOISE CONSIDERATIONS IN THE DESIGN OF MAGNETIC FILM SENSE AMPLIFIERS

Abstract

A model of a magnetic film sense system is presented. Using the model the mean time between false readouts due to random noise is determined as a function of the system parameters; total magnetic flux switched, switching time, sense line resistance, amplifier noise factor and linear amplifier filter efficiency. (The filter efficiency with respect to a given input pulse shape is the signal-to-noise ratio at the output of the amplifier divided by the corresponding signal-to-noise ratio at the output of a filter matched to the pulse shape.) The degradation of signal-to noise ratio caused by introduction of a quick recovery 'short' time constant is determined and shown experimentally.
