The threshold voltage
WebJan 31, 2024 · Hence, V 1 is an upper threshold voltage (V UT). The output will remain low until the input signal is less than V. when the output of the Schmitt trigger is low, in this condition, Now, the output remains high until the input signal is less than V 2. Hence, the V 2 is known as a lower threshold voltage (V LT). Non-Inverting Schmitt Trigger WebTo accumulate mobile electrons below the oxide, the gate voltage VG has to be sufficiently high to cross the “threshold”. This is governed by a number of factors. The work-function difference between the gate and the silicon substrate (this leads to the “flatband” voltage). The gate voltage component required to bring about surface ...
