How to size a NAND gate? What happens if PMOS is used for pull-down and NMOS is used for pull-up? What is the output range in this case?
cmos circuit structure questions. Connect input and output with a resistor
There was a PLL block diagram on the white board that I drew earlier for previous interviewers. The engineering manager pointed to the diagram and asked me to tell him about the functionality.
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
One of the engineers pulled out his text book and asked how to do a delta to Y conversion. The other engineer interviewing said, "I don't even know how to do that" and he admitted that he had just looked it up that morning.
