Question: how cmos can be used as an inverter?
Answer: CMOS Inverter Basics Both gates are connected to the input line. ... You can easily see that the CMOS circuit functions as an inverter by noting that when VIN is five volts, VOUT is zero, and vice versa. Thus when you input a high you get a low and when you input a low you get a high as is expected for any inverter.
