Analog Devices Associate Test Engineer Interview Questions and Answers

Q1. Capacitor and voltage in series and parallel
Ans. 
Capacitors in series add reciprocally, in parallel add directly. Voltage in series is the sum, in parallel is the same.
• Capacitors in series: 1/Ctotal = 1/C1 + 1/C2

• Capacitors in parallel: Ctotal = C1 + C2

• Voltage in series: Vtotal = V1 + V2

• Voltage in parallel: Vtotal = V1 = V2

Q1. Analyse the output of the circuitry
Ans. 
The output of the circuitry needs to be analyzed for functionality and accuracy.
• Examine the input and output signals to ensure they are within expected ranges

• Check for any noise or interference in the output

• Verify that the circuit is functioning as designed based on the specifications

• Look for any potential issues or errors in the output

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

Q1. Difference between sanity and smoke
Ans. 
Sanity testing is a narrow and deep testing approach to check if the specific functionality is working fine after changes, while smoke testing is a broad and shallow testing approach to check if the software build is stable enough for further testing.
• Sanity testing focuses on specific functionality, smoke testing checks overall stability

• Sanity testing is usually performed after a specific change, smoke testing is perfo...read more

Q2. Difference between regression n retesting
Ans. 
Regression testing is testing the entire application after changes, while retesting is testing specific areas after fixes.
• Regression testing is done to ensure that new code changes do not affect existing functionality.

• Retesting is done to verify that a specific bug or issue has been fixed.

• Regression testing involves running the entire test suite, while retesting focuses on specific test cases.

• Example: After fixing a bu...read more

Q3. Find repetitive words in string program
Ans. 
Program to find repetitive words in a string
• Split the string into words using a delimiter like space

• Create a hashmap to store word frequencies

• Iterate through the words and update the hashmap

• Identify words with frequency greater than 1 as repetitive
