Abstract:

This paper presents an analog inverse-matrix-vector multiplication (IMVM) solver that addresses the input loading limitation of prior crossbar-based implementations. The proposed decoupled input injection scheme isolates the input circuit from the crossbar array, enabling the use of smaller crossbar conductance for lower power consumption and relaxing the required op amp …

Abstract:

As crossbar-based analog computing grows in popularity for high-speed, energy-efficient processing, the need to drive discrete-time signals to heavy loads arises. This paper presents a novel bi-slewing CMOS driver utilizing high slew-rate error amplifiers and a push-pull stage. The proposed driver achieves a measured settling time of 8.5 ns and a …
