Improving the Performance of the Sense-Amplifier Circuit Through Pre-Amplification Strobing and Noise-Matched Clipping

Abstract

For the improvement of the performance of the sense-amplifier circuit for conventional ferrite-core memories, the principles of pre-amplification strobing and noise-matched clipping are proposed and discussed. A circuit incorporating these principles and achieving notable reliability and economy is described. The circuit is suitable for working with short cycle times and low signal-to-noise ratio values and can be used to process matrices of sizes considerably larger than 4096 cores.
