  • Abstract
    A bandgap reference circuit which operates at supply voltages down to 1.2V is presented. It offers a reference voltage of 82mV and a reference current of 2¿A with a temperature dependence of less then 100ppm/K in a temperature range form ¿40°C to 120°C. The power supply rejection is enhanced by self biasing the circuit with the reference current. The circuit has been fabricated in a standard 1.5¿m CMOS process.
