This paper presents a CMOS voltage reference (CVR) with low power, high power supply ripple rejection (PSRR), and small area operating in a wide temperature range. The proposed circuit contains only MOSFETs biased in subthreshold region and operates based on compensated Δ V of two different-type transistors. Implemented in a standard 0.18Μm CMOS process, the measured reference voltage of the proposed CVR is 344 mV with standard deviation of only 2.89 mV and achieves an average TC of 46.2ppm°C over a wide temperature range from - 40 °C to 125°C without individual chip-by-chip trimming. The measured PSRR is -70 dB, -51 dB and -52 dB at 10 Hz, 100 kHz and 10 MHz, respectively. The measured line sensitivity (LS) is 0.25%/V while consuming 15.65nW at 0.5V supply. The active area is 0.019mm
