Rohm Semiconductor Analog Design Engineer Interview Questions and Answers
Rohm Semiconductor Analog Design Engineer Interview Experiences
1 interview found
I applied via Campus Placement and was interviewed before Dec 2021. There were 3 interview rounds.
First round is written test and they asked descriptive questions related to CMOS single stage amplifiers, differential amplifiers, RC circuits, Network theory, Bode plots, poles and zeros concepts
They asked the questions based on my answers which I wrote in written test. Then they some more questions related to that questions. Overall time is 40-60 minutes.

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.

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

- Q1. Nmos design and working
- Ans.
NMOS (N-channel Metal-Oxide-Semiconductor) is a type of MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) that uses n-type semiconductor for the channel.
NMOS transistors are used in digital and analog circuits for switching and amplification.
In NMOS design, the gate is made of metal, the insulator is made of oxide, and the semiconductor is n-type.
NMOS transistors operate by applying a voltage to the gate termi...
- Q2. CMOS circuit and design along with VTC characteristics
- Ans.
CMOS circuits are widely used in integrated circuits for their low power consumption and high noise immunity. VTC characteristics show the relationship between input and output voltage.
CMOS circuits consist of complementary pairs of p-type and n-type MOSFETs, allowing for low power consumption and high noise immunity.
VTC (Voltage Transfer Characteristic) shows the relationship between input and output voltage in a CMOS...
