This paper proposes a process, voltage, temperature (PVT) independent Schmitt trigger with fully adjustable hysteresis threshold voltages. These characteristics are attributed to the proposition of a self-tuning circuit in the inverter-comparator, along with a feedback controlling network for hysteresis characteristic. The proposed Schmitt trigger is designed and fabricated with SMIC 0.13 µm CMOS technology. It has much less power consumption of only 2.51 µW, and features also an adjustable
