opamp basics
Mostly very basic Device Physics questions. Not very complicated and some of the questions were: 1. Describe the operation of NMOS and PMOS, 2. What is body effect? How does it affect the gate voltage. 3. Describe the operating regions of NMOS transistor 4. If gate voltage is 2V and drain voltage is is 2V what is the source voltage? 5. What factors affect threshold voltage? Explain them 6. What is channel length modulation?
How does the charge pump current impact the phase noise of PLL
