In this paper, a nanopower supply-insensitive complementary metal-oxide-semiconductor (CMOS) unit threshold voltage (Vth) extractor circuit is proposed. It meets the contemporary industry demand for portable devices that operate with very low power consumption and small output sensitivity. An α times Vth (α Vth) extractor is also described, in which α varies continuously. Both incremental and decremental α Vth voltages are obtained. A post-layout simulation results using HSPICE with CMOS 0.18 um process show that the proposed unit α Vth extractor consumes 265nW of power given a 1.6 V power supply. Sensitivity to temperature is 0.022%/°C ranging from 0°C to 100°C. Sensitivity to supply voltage is 0.027%/V.
