Abstract: A Bandgap Voltage Reference (BVR) is a circuit whose output is independent to variations temperature, process, supply voltage and noise. It is required in many integrated circuits to ensure their proper functionality. A current mode approach OTA based Bandgap Voltage Reference design is proposed in this project. In this report, literature review on BVR was conducted, followed by a proposed BVR design and simulation results. The proposed design is being implemented with IBM 0.13um CMOS process. It is found to achieve an output voltage of 546mV. It is able to work at a minimum voltage of 1.2V. It has a temperature coefficient of 10.6ppm/°C for a temperature ranges from -45°C to 125°C. It achieves 85.6dB power supply rejection ratio at DC with 0.013mV/V line regulation.
