| Title | Design of a Low Voltage High PSRR Voltage Reference Using Current-Mode Approach |
| Summary | Voltage reference has been used widely in ADCs and DACs to specify their input or output ranges. For high resolution data conversion applications, the requirement for the accuracy and stability of the reference voltage is quite stringent. Typically speaking, the desired behaviour of a reference voltage is that it stays at a particular value regardless of change in temperature (between -40 to 140 deg C), aging process variation or power supply variation/noise. The goal is to design a voltage reference with a Temperature Coefficient (TC) < 30 ppm/deg C, PSRR (Power Supply Rejection Ratio) > 60 dB, and operating power supply range of 1.8V down to 1.2V. Thus current mode approach is required. Student is expected to use the Cadence EDA tools for circuit simulation for 55nm BCD-lite technology. Only if time permits, circuit layout for completeness with post layout simulations could be included. This project is most suitable for student in the electronic option with specialization in IC Design with a good knowledge in analog circuits. |
