Abstract

In this paper, a nanopower supply-insensitive complementary metal-oxide-semiconductor (CMOS) unit threshold voltage (V_th) 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 V_th (α V_th) extractor is also described, in which α varies continuously. Both incremental and decremental α V_th voltages are obtained. A post-layout simulation results using HSPICE with CMOS 0.18 um process show that the proposed unit α V_th 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.
