COMPLETE SOLUTIONS GUARANTEED
⫸ When analyzing CMOS, what do you assume and then check at the
end? Answer: Saturation. If wrong in end, redo the analysis and
assume triode region
⫸ What does a MOSFET act like when operating in the triode or
linear region? Answer: Like a voltage-controlled resistor. The drain
current increases with the drain-source voltage
⫸ What happens to the parts of a MOSFET when operating in
saturation? What does the MOSFET act like? Answer: The drain
current is nearly constant as VDS increases, so it acts like a voltage-
controlled current source. Used in amplifiers
⫸ What are the units of Cox? Answer: F/m^2
⫸ What is the equation for Cox? Answer: Epsilon(ox)/thickness(ox)
⫸ What is Epsilon(ox)? Answer: permittivity
⫸ What is the permittivity of silicone dioxide? Answer: 3.9
, ⫸ What is epsilon 0? Answer: 8.854 * 10^-12 F/m
⫸ What is the equation for Kn'? Answer: Mu*Cox
⫸ What are the units for Kn'? Answer: A/V^2
⫸ What does PMOS look like? Answer:
⫸ What does NMOS look like? Answer:
⫸ When the gate is connected to the drain, what region is the CMOS
operating in? Answer: Saturation
⫸ When the gate is connected to the drain, what is true about their
voltages? Answer: they are equal in magnitude
⫸ What is another equation for ro in terms of the drain-source
voltage and drain current? IF gate-source voltage is constant? Answer:
ro=delta VDS/ delta iD
⫸ What is VA equal to? IF gate-source voltage is constant? Answer:
~Drain Current * ro
⫸ What is the first step for analyzing transistor amplifier circuits?
Answer: perform DC analysis. Calculate the small signal parameters
