Q2. Draw a half wave rectifier.
Ans. 
A half wave rectifier is a simple electronic circuit that converts AC voltage to pulsating DC voltage.
• Consists of a diode connected in series with a load resistor

• Allows only the positive half cycle of the input AC signal to pass through

• Output voltage is the same as the input voltage during the positive half cycle

Q3. How does a CMOS function
Ans. 
CMOS functions by using both NMOS and PMOS transistors to create logic gates and memory cells.
• CMOS stands for Complementary Metal-Oxide-Semiconductor

• It uses both NMOS (n-type) and PMOS (p-type) transistors to create logic gates and memory cells

• CMOS technology is widely used in digital integrated circuits due to its low power consumption and high noise immunity
