摘要

Bandgap reference (BGR) circuits play a key role in maintaining precise voltage references crucial for the operation of modern integrated circuits (ICs). With the continuous drive towards lower supply voltages and higher energy efficiency, the demand for BGR circuits capable of operating at ultra-low voltages has increased. This review paper presents a comprehensive analysis of recent advancements and emerging trends in the design of low-voltage BGR circuits modified for sub-1 V supply voltages. Through critical analysis and synthesis of recent literature, the paper explains novel methodologies, design strategies, and technological innovations employed in the development of robust and efficient low-voltage BGR circuits. The review researches into various areas such as circuit topologies, semiconductor fabrication techniques, and temperature compensation mechanisms, highlighting the underlying principles and design considerations shaping the evolution of low-voltage BGR circuits. Specific applications, such as IoT devices, biomedical systems, and energy-harvesting circuits, demonstrate the practical significance of these advancements. Furthermore, by identifying key challenges—such as thermal stability, voltage sensitivity, and adaptation to new CMOS technologies—the paper outlines pathways for future research and innovation in BGR circuit design. This review aims to inspire researchers and engineers to develop energy-efficient and reliable voltage references, driving progress in next-generation semiconductor electronics.
