\textbf{2.2.3 Questions about the open loop AC Simulation}\\\\  \textbf{1. What are the operating points? At which states (saturation, linear) the transistors are operating?}\\  \textbf{The following table shows the operation points of all the transistors.} \\  Initially, all the transistors were operating in saturation state except for transistors M8 and M5, who were in linear state. The transistor M5's dimensions were then tuned to 4 instead of the previous calculation of 3. As a result M5 moved to the saturation state. Hence state but M7 changed to linear case as evident from the relation between the dimensions of M5 and M7. So M7 was also tuned from the previous value of 10 to 18.75 .As a result,  all the transistors were in saturation, except for M8, which was in linear, as expected.\\\\ expected. All this process was actually done to avoid the recalculation of the entire pre-exercise.\\\\  \textbf{2. What is the -3dB frequency of the op amp?}\\  2.006 KHz \\\\  \textbf{3. What is the DC gain?}\\
