Vertafore Application Support Engineer 1 Interview Questions and Answers

Q1. Proof of Regions of operations of Mosfets in CMOS inverter.
Ans. 
The regions of operation of MOSFETs in a CMOS inverter are cutoff, triode, and saturation.
• MOSFET operates in cutoff region when Vgs < Vth

• MOSFET operates in triode region when Vgs > Vth and Vds < Vgs - Vth

• MOSFET operates in saturation region when Vgs > Vth and Vds > Vgs - Vth

• CMOS inverter uses both NMOS and PMOS transistors to achieve high noise immunity and low power consumption

Q1. Explain the power leakage and dynamic power in CMOS circuits.
Ans. 
Power leakage is the power dissipated in CMOS circuits when transistors are in off state, while dynamic power is the power dissipated during switching.
• Power leakage occurs due to subthreshold leakage currents in transistors when they are in off state

• Dynamic power is the power dissipated during charging and discharging of capacitive loads in CMOS circuits

• Power leakage increases with decreasing transistor size, while dyn...read more

Q1. What is Acceleration?
Ans. 
Acceleration is the rate of change of velocity of an object with respect to time.
• Acceleration is a vector quantity, meaning it has both magnitude and direction.

• It is measured in meters per second squared (m/s^2).

• Acceleration can be positive (speeding up), negative (slowing down), or zero (constant speed).

• Examples of acceleration include a car accelerating from a stop sign, a roller coaster going down a hill, and a rock

Q2. Rate of change of velocity.
Ans. 
Rate of change of velocity is known as acceleration.
• Acceleration is the derivative of velocity with respect to time.

• It is measured in meters per second squared (m/s^2).

• Positive acceleration means speeding up, negative acceleration means slowing down.

• Examples of acceleration include a car accelerating from a stop sign or a roller coaster going down a hill.

Q2. 32 bit vs 64 bit Computer Architecture
Ans. 
32 bit architecture can address up to 4GB of RAM, while 64 bit can address much more.
• 32 bit architecture has a maximum addressable memory of 4GB

• 64 bit architecture can address much more memory, up to 16 exabytes

• 64 bit architecture can perform more calculations per clock cycle

• 64 bit architecture is required for running certain software, such as Adobe Creative Suite

• 32 bit architecture is still commonly used in older syst
