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!
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
