The interviews were pretty much technical. The first interviews was on projects that I worked on. In the second interview I was asked specific technical questions on ADCs, Opamp classes, buck and boost converters also question like how will I go about coding this etc.
What is the SNR? What is the difference between inverting and non-inverting amplifier? Describe the process how to debug a failure on a PCB board.
Programming: Implement a clock in any language you want. SPI, Significance if clock/duty cycle measurements
Draw two stage CMOS amplifier explain its operation derive gain and output impedance number of poles and zeros and find them comment on stability and frequency compensation
Noise analysis of different circuits
The question about PLL finally got me stuck.
Everything is technical, but maybe simple. Admittedly, I don't know every answer, but I tried to analyze things and just get through the quesitons. This is the most technical interview I had ever experienced during my job search.
- Verilog questions on conditional equality vs. logic equality operators, automatic and static keywords, inertial and transport delays. - Working of I2C (listed on resume) - Verifying a design - LDO, ADC models
One of the questions they asked is about the LDO.
questions were mainly based on the mosfet and cmos area
