Interview Questionnaire
8 Questions
- Q1. Output Response of RLC circuits
- Ans.
The output response of RLC circuits is the behavior of the circuit's output voltage or current over time.
The output response depends on the values of the resistance (R), inductance (L), and capacitance (C) in the circuit.
RLC circuits can exhibit different types of responses, such as overdamped, underdamped, or critically damped.
The response can be analyzed using differential equations or Laplace transforms.
For example,...
- Q2. Effect of temperature on Leakage current
- Ans.
Temperature has a significant effect on leakage current in analog circuits.
Leakage current increases with temperature due to increased carrier generation and diffusion.
Higher temperatures can cause increased leakage current through reverse-biased junctions.
Temperature coefficients are used to quantify the change in leakage current with temperature.
Thermal management techniques are employed to minimize the impact of tem...
- Q3. Some Tricky questions on KCL and KVL
- Q4. Complex RC circuits
- Ans.
Complex RC circuits are circuits that contain resistors and capacitors in a series or parallel configuration.
The time constant of a complex RC circuit can be calculated using the product of resistance and capacitance.
Complex RC circuits can be used in filters, oscillators, and timing circuits.
The behavior of a complex RC circuit can be analyzed using circuit analysis techniques such as Kirchhoff's laws and nodal analys
- Q5. Effect of opamp's bandwidth
- Ans.
The bandwidth of an opamp affects its ability to amplify high-frequency signals.
Opamp bandwidth determines the range of frequencies it can amplify effectively.
A higher bandwidth allows the opamp to amplify higher frequency signals accurately.
A lower bandwidth limits the opamp's ability to amplify high-frequency signals.
Opamp bandwidth is typically specified in terms of the -3dB frequency.
Bandwidth can be improved by us...
- Q6. Question on power dissipation in a CMOS circuit
- Q7. Bode Plot Analysis
- Q8. One valid reason, why you won't go for a MS, apart from financial crisis
- Ans.
Prefer gaining industry experience over academic research
Desire to gain practical experience in industry
Interest in applying knowledge in real-world projects
Preference for hands-on learning and problem-solving in a work environment

Interview Preparation Tips
Experience: Texas Instruments is the first semiconductor company visiting the campus. The selection procedure involves a screening test, a technical interview and a final HR interview. Pointer cutoff will generally be 6 or 7, and PCs can even request to not have any cutoff if there are enough resources (computers) to conduct online screening test.
General Tips: Department courses such as Analog Electronics, Linear Signals and Systems, Linear Control Systems, Linear Integrated Circuits are very important. More emphasis is given to Network Theory and Feedback theory. Questions will be tricky in the sense that you might not have seen them before, but can be solved with intuition and less math. By intuition, I mean the answers follow from application of basic principles of network theory (superposition, Thevenin etc). Very good articles on Network and Feedback theory can be found at Prof. KRK Rao's website.
Skill Tips: In the interview, it is okay if you don't know the answer to any question. But try to use the hints provided by the interviewer and solve the problem. They are more concerned about your approach rather than the answer.

- Q1. Basic questions of circuit theory and analog
- Q2. Bode plot questions
- Q3. Rc network with constant current source
- Ans.
An RC network with a constant current source is used to create a voltage output that is proportional to the input current.
RC network consists of a resistor (R) and a capacitor (C) connected in series or parallel.
Constant current source ensures a steady current flows through the network.
The voltage output across the RC network is determined by the time constant (RC) and the input current.
This configuration is commonly u

I applied via Campus Placement and was interviewed in Aug 2022. There were 2 interview rounds.
90 minutes with 20 questions of Analog and Aptitude each. Topics are Basic Network Theory, Diode, Op-amps, etc. Topics may vary place-to-place.
(6 Questions)
- Q1. Questions are cumulative: Draw a Lowpass filter (RC)
- Q2. Add capacitor parallel to one resistor and tell frequency response
- Ans.
Adding a capacitor in parallel to a resistor changes the frequency response of the circuit.
The cutoff frequency of the circuit decreases as the capacitance increases.
The circuit becomes a high-pass filter with a -20dB/decade slope above the cutoff frequency.
The impedance of the capacitor decreases as frequency increases, allowing more current to flow through the circuit.
The resistor and capacitor form a voltage divider...
- Q3. Add resistor to the capacitor and tell frequency response
- Ans.
Adding a resistor to a capacitor changes the frequency response of the circuit.
The cutoff frequency of the circuit decreases with increasing resistance.
The circuit becomes more attenuative at higher frequencies.
The time constant of the circuit increases with increasing resistance.
The circuit becomes more stable and less prone to oscillation.
