Important Interview Analog Circuits Answers Analog Interview Questions by VLSI Universe - May 2, 2020July 21, 20210 The section contains analog circuits questions and answers on Resistor networks, transistor MOSFET, current mirror, Opamp, and RC circuits (transient analysis). Answer 1. Answer 2. If RC >> T, then the circuit acts as an integrator. If RC << T, Here the time constant is very small, so the capacitor will be charged very fast and the output voltage almost follows the input voltage. Answer 3. Given a DAC circuit so the value 1010 corresponds to the 10 in decimal and it is 4-bit. Therefore the least significant bit will be equaled to Vred/16 = 8/16 = 0.5V. Hence the value 1010 is 0.5*10 = 5V. One more method by using a superposition theorem also it can be solved. Answer 4. Vthe = 400mV. The

Cadence Analog Interview Written Questions 2020 Analog Interview Questions by VLSI Universe - May 1, 2020July 21, 20210 The written test analog questions were asked in the cadence interview process. RC circuits and Op-Amp questions are important. The interview process started in the early morning in their company building. We were around 12 students from the same college. The HR alone met us. The cadence HR took two rounds of written tests Digital and Analog. The digital written test round was a bit easy. Verilog and basic digital circuit design based on problem statement questions were there. And the analog written test was tough, so many in-depth questions were there. Knowledge network theory and series RLC circuits were a must need. The shortlisted students for both sections separately. Few aspirants were selected for both analog and digital profiles. Then they conducted
