Exicom Test Engineer Interview Questions and Answers for Freshers

Q1. Explain the MOSFET operation and Body Bias effect
Ans. 
MOSFET is a type of transistor used in electronic devices. Body Bias effect refers to the change in threshold voltage due to biasing of the body terminal.
• MOSFET stands for Metal-Oxide-Semiconductor Field-Effect Transistor.

• It has three terminals: Gate, Source, and Drain.

• The operation of a MOSFET involves controlling the flow of current between the Source and Drain terminals by applying a voltage to the Gate terminal.

Q1. Capacitor and voltage in series and parallel
Ans. 
Capacitors in series add reciprocally, in parallel add directly. Voltage in series is the sum, in parallel is the same.
• Capacitors in series: 1/Ctotal = 1/C1 + 1/C2

• Capacitors in parallel: Ctotal = C1 + C2

• Voltage in series: Vtotal = V1 + V2

• Voltage in parallel: Vtotal = V1 = V2

Q1. 1.What is op amp 2.In the 5 resistance connect in parallel each one have 5ohms and 50 v DC supply what is current in circuit. 3.What are the units of inductance and capacitance. 4.starters
Ans. 
Op amp stands for operational amplifier, used in electronic circuits for amplifying signals.
• Op amp is a high-gain electronic voltage amplifier with differential inputs.

• It is commonly used in signal processing, audio amplification, and instrumentation.

• Op amps have two inputs, inverting and non-inverting, and one output.

• They are often used in feedback circuits to control gain and performance.
