| Popis: | A bandgap voltage reference circuit using a curvature elimination approach is proposed. Curvature elimination is achieved by a weighted subtraction of the outputs of two basic bandgap circuits that have the same functional form as the curvature. The reference is implemented in a 130nm CMOS process and generates a nominal output voltage of approximately 1.24V. Simulation results predict the proposed circuit can achieve a temperature coefficient of 0.5ppm/°C over the temperature range from 0°C to 100°C. |
