1) compare 2 NFET devices with same W/L. One device has bulk connected to GND and the other has bulk connected to -1v. Drain is fixed at 1v. What device is faster? Why? Explain the body effect and why it affects the device threshold.
Circuit Designer Interview Questions
40 circuit designer interview questions shared by candidates
What happens if the common mode voltage drops at the input with the current sources? i.e.
Draw 2 stage OPAMP. Explain how to calculate open loop gain. Explain stability and Miller effect. How is the Miller cap implemented? What are the drawbacks? How do I make the amplifier faster?
Draw a circuit for level shifting and attenuation
Draw an inverter and asked a lot of questions based on that. Fall/rising time matching, how the current changes...
First, the interviewer asked me lots of things about my resume such as talk about the project you think it most hard, what if your teammate have different idea with you, talk about an experience that you have influence your teammate... Then, I did some technical questions: Use nand gates, inverters to build nor gate such kinds of things. Design a elevator (verilog/finite state machine) and some follow ups.
