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.

LDO output noise
What is the difference between == and === ? What is the use of reg in verilog?
Very basic questions(which were easy if we come out of college or recent grad but very unexpected for an experienced candidate, since we don't need to do all that at hand calculation level everytime), Although figured out most of them but couldn't give satisfactory answers as I was rusty in few topics(my mistake too, could review those concepts because of poor time management) The recruiter was pretty rude too, which again was kind of demotivating, especially when we try to figure out things on which we turned rusty.
1. Basic questions around transistors - particularly large W/L ratio ones. 2. A couple of circuits with pmos and nmos in a current mirror configuration - I was asked what would be the node voltages as a function of input to one of the transistor's gate. 3. Layout/cross section of inverter and small signal model of MOSFET
presentation part II:
BJT with 1kohm from emitter to gnd, and 1kohm from collector to +5V. What are the emitter and collector voltages as you adjust base voltage from 0 to 5V
Regarding the input diff pair, how do you minimze offset?
Explain miller compensation
