提出了一种与工艺、电压、温度(PVT)无关的施密特触发器,该触发器具有完全可调的迟滞阈值电压。这些特性是由于在反相比较器中引入了自校正电路,并沿着了滞环特性的反馈控制网络。该施密特触发器采用SMIC 0.13 μm CMOS工艺设计和制作。它具有更低的功耗仅为2.51 μW,并且还具有可调的滞后阈值电压范围从350 mV到850 mV,最小电源电压为1.0 V。所有这些优点使其非常适合在低功率感测节点中作为1位数字化工作。
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 hysteresis threshold voltages ranging from 350mV to 850mV at a minimum supply voltage of 1.0V. All these advantages make it very suitable to work as 1-bit digitization in a low power sensing node.
