Abstract:
An ultra low-voltage and low-power CMOS voltage reference using subthreshold, body effect and switched-capacitor techniques is proposed in this paper. No resistor and BJT is used in this structure. The proposed circuit has been simulated with Chartered 0.18-¿m CMOS process. The simulated results show that the voltage reference can operate with sub-0.6V supply and total supply current is 210nA at 0.58V supply. The temperature coefficient of 7.67ppm/°C for a temperature range of -40°C to 85°C is achieved. The layout area is only 0.018 mm2.
