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

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

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

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.
