LDO output noise
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.
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.
What is the difference between == and === ? What is the use of reg in verilog?
presentation part II:

Regarding the input diff pair, how do you minimze offset?
Explain miller compensation
