Abstract

A new systematic approach is used for the design of bandgap references. A linear combination of two base-emitter voltages is taken to compensate implicitly for the temperature behavior of these base-emitter voltages. To reach optimum circuit performance with respect to accuracy and power, systematic design procedures are used. The realized bandgap reference circuit is completely integratable and operates from a supply voltage of only 1V. The output voltage is approximately 194 mV and has an average temperature dependency of 1.5ppm/°C in the range of 0°C to 100°C. The circuit has been realized in a bipolar process withf t ⩾ 5 GHz. The total amount of capacitance is approximately 150 pF and the current consumption is about 100µA.
