AI Thread Summary
In CMOS inverters, $V_i=L$ indicates that the input voltage is approximately at ground level, while $V_i=H$ signifies that the input voltage is close to the supply voltage, $V_{dd}$. This distinction is crucial for understanding the inverter's function as a logical NOT gate. The inverter operates by switching its output based on these input voltage levels. Overall, these voltage levels are fundamental to the operation of CMOS technology.

Hello.
Can someone explain to me what does $V_i=L$ and $V_i=H$ mean in CMOS inverters?

Thank you so much!
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
