What is differential amplifier gain? How can you increase it? How can you play with the parameters which will affect differential amplifier gain?
Rfic Design Engineer Interview Questions
82 rfic design engineer interview questions shared by candidates
Basic questions about things on resume. how was the group project. Some questions about IC.
Many in depth technical questions about circuits, systems, testing, analog, RF
two tone test, finding gain and impedance, filters, etc
Mainly questions that relates a full understanding of RF and microwave engineering.
1. A question on low-pass filter for current input and output. 2. A question on the loop stability of a PLL. What could be done to improve the stability? 3. A question on a passive switched-cap circuit with multiple clock phases. 4. A question on R-ladder and which node has the largest noise voltage (rms) 5. Multiple RC circuit questions with pulse and step inputs on different R and C combos and different structures. 6. A question on VCO phase noise; a question on the effect of duty cycle variation on phase noise. 7. A question on VCO swings (Q-factor/ bias current etc).
the first round a question on network analysis then second question about voltage swing of mos amplifier. then some question of lna and then interviwer ask about my projects and internship
Following questions about your phd presentation.
common mode rejection analysis.
On site they were highly non-professional. They asked me to draw design schematics of my current employer. They do things hastily and try to create pressing environment so that you can tell them something. If you are going from big names like Mediatek, Samsung, Qualcomm or Broadcom then be careful, they are bunch of beginners who are trying to interview many people everyday so that they can get to know good design toplogies and try to copy over. This is just what I felt.
