Abstract: The project focuses on designing and simulating a Bandgap Voltage Reference (BGR) circuit using 180nm CMOS technology to achieve a temperature-independent and precise voltage reference. This is crucial for reliable operation of analog and digital components. The design uses Complementary-To-Absolute-Temperature (CTAT) and Proportional-To-Absolute-Temperature (PTAT) characteristics to cancel out temperature effects and generate a constant reference voltage. The circuit is suitable for various applications, including Analog-to-Digital Converters, voltage regulators, temperature sensors, and battery-operated systems. The work not only demonstrates temperature compensation techniques but also enhances understanding of analog circuit behaviour under real-world conditions.
Keywords: Cadence, simulation, circuit, voltage.
