A voltage reference of low supply voltage and low power consumption has been proposed and simulated using 0.18µm process in this paper. Utilizing the body effect, temperature compensation is achieved without using any other special devices such as thick gate oxides MOSFETs with higher threshold. The simulation results show that the line sensitive is 0.73ppm/V in a supply voltage range of 0.6V to 2V and the temperature coefficient is typically 23.7ppm/°C in a temperature range of −20°C to 80°C with the power consumption of 30.5nW at room temperature. The power supply rejection ratio is −40dB at 10Hz and −32dB at 100Hz, respectively.
