A 619-pixel machine vision enhancement chip based on two-dimensional semiconductors.

ABSTRACT: The rapid development of machine vision applications demands hardware that can sense and process visual information in a single monolithic unit to avoid redundant data transfer. Here, we design and demonstrate a monolithic vision enhancement chip with light-sensing, memory, digital-to-analog conversion, and processing functions by implementing a 619-pixel with 8582 transistors and physical dimensions of 10 mm by 10 mm based on a wafer-scale two-dimensional (2D) monolayer molybdenum disulfide (MoS₂). The light-sensing function with analog MoS₂ transistor circuits offers low noise and high photosensitivity. Furthermore, we adopt a MoS₂ analog processing circuit to dynamically adjust the photocurrent of individual imaging sensor, which yields a high dynamic li
