1. Given a common gate transistor with a capacitor between source and gate , and drain terminal grounded , calculate the impedance seen by ac signal from source . 2. Given an OP-AMP circuit and to find output voltage , which involves KCL type solving PS: The interviewer is calm and friendly - He was telling that he visited 4 campuses including one IIT- M -- where he didn't find good talent from UG , PG from there as well . So, you might now , of what standard he is expecting . This interviewer is my eye opener . To be a successful Analog engineer, you may require a lifetime !!!!
