    Abstract
    A low-supply, nano-watt level CMOS-only voltage reference is proposed in this paper for the internet-of-things, wireless sensor networks, and implantable biomedical chips. The threshold voltage fluctuation caused by the process variation can be suppressed to within 30 mV through utilizing the threshold voltage difference between thick-gate transistors and thin-gate transistors. Benefiting from the self-regulating technology and subthreshold operation, the circuit branches and supply voltage are significantly decreased compared with the previous CMOS voltage reference, which...
