analog basics ,mosfet basics, cmos, digital electronics
Draw a common source amplifier and derive its gain. How is small signal model explaining the amplifiers behaviour?
Find the output voltage using kcl kvl in the given resistor circuit
Diode and it's working with diagram.
Whats the difference between Analog and Digital Signals and why do we need AC and DC signals, RC numericals, Mosfets, Opamps and a bit about resonance
Basic analog and digital questions Some amplifier based
1. What is antenna error? How to prevent antenna error? 2. What type of antenna diode placed for PMOS and NMOS device? What is antenna ratio? 3. How we can avoid the antenna without using jumper and antenna diode? 4. What kind of charges will have generated during plasma etching? How diode works? 5. Explain latch up? How guard ring avoids the latch up? In Guard ring we are using metal1, it has some resistance then how it will help to reduce the resistance. 6. How you create the latch up in inverter without having spike? 7. L=1um W=1um and L=10um W=10um sheet resistance is 1ohm find R? If 1um carries 1mA. How much current carries 10um width of metal? How it possible if both metals having same resistance.
