Design and optimization of a Bandgap Voltage Reference Circuit

The design and optimization of a Bandgap reference circuit, a critical component in the area of Analog and mixed-signal integrated circuits This research presents a comprehensive study on the design. Bandgap voltage references are essential for providing stable and temperature-independent voltage references, crucial for ensuring accurate and reliable operation of various electronic systems. The proposed design employs a combination of hybrid bipolar and Complementary Metal Oxide Semiconductor (CMOS) transistor technologies in order to provide a stable and temperature–compensated output voltage. The study investigates several circuit topologies and evaluates their performance using metrics like line regulation and temperature coefficient. The outcomes of the simulation demonstrate that the suggested structure works to achieve a low temperature coefficient. The optimized bandgap reference exhibits superior performance compared to existing designs, making it well-suited for applications demanding high precision and reliability, such as voltage regulators, analog-to-digital converters, and sensor interfaces.
