  4. Abstract:
  5. A novel, precision current reference with low temperature and supply sensitivity and without any external component has been designed in a 0.18μm CMOS mixed-mode process. The circuit is based on a bandgap reference (BGR) voltage and a CMOS circuit like a beta multiplier. The simulation results show max-to-min fluctuation of about 1% over a temperature range of -20°C to +100°C and supply voltage range of 1.1V to 2V with ±30% tolerance for all of the used on-chip resistors. The maximum nominal current variation in process corners is less than 3.5%. © 2003 IEEE
