A 0.6-V, 1.56-nW, 5.87-ppm/°C, 0.23%/V CMOS-Only Subthreshold Voltage Reference with the Threshold Voltage Difference

Xin Xin et al.

Summary: This paper proposes a low-supply, nano-watt level CMOS-only voltage reference for the internet-of-things, wireless sensor networks, and implantable biomedical chips. By utilizing the threshold voltage difference between thick-gate transistors and thin-gate transistors, the threshold voltage fluctuation caused by process variation can be suppressed. The circuit branches and supply voltage are significantly decreased compared with previous designs, allowing for low power design.
