This paper presents a novel picowatt CMOS voltage reference for energy harvesting (EH) system applications.The output voltage is 133.6mV with subthreshold operations of MOSFETs at a supply of 0.5V. It was simulated in 0.18-μm CMOS technology. The simulation results show voltage variation of 0.594%/V line sensitivity for supply voltage from 0.5V to 3V and about 3ppm/°C of temperature variation from -20°C to 80°C. Its power consumption is only 205.027pW. The power supply rejection ratio (PSRR) has been kept stably at -41.99 dB up to GHz level.
