A Current-Mirroring Voltage Buffer for Analog Read-Out in Memristor Crossbar Arrays

Conference on Ph.D. Research in Microelectronics and Electronics, pp. 1–4

Abstract

Memristive crossbar arrays enable fast and efficient implementation of analog vector-matrix multiplication as hardware accelerators for computational neural networks. The individual analog building blocks for precise and reliable operation play a key role for the resulting performance. This paper presents a voltage buffer with high speed current sensing for fast read-out of the multiplication results. An operational amplifier with two current matching outputs is proposed as viable alternative to classic TIA based designs.
