Q1. Explain CMOS inverter?
Ans. 
CMOS inverter is a type of digital logic gate that implements logical NOT operation.
• CMOS inverter consists of a PMOS transistor connected in series with an NMOS transistor.

• When input is high, PMOS conducts and NMOS is off, output is low.

• When input is low, NMOS conducts and PMOS is off, output is high.

• CMOS inverters are widely used in digital circuits for logic operations.

• Example: Inverter gate in a CMOS technology-base
