\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?}\\  . The following table shows the operation points of all the transistors. \\  Initially, all the transistors are 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 all the transistors were in saturation, except for M8, which was in linear, as expected.\\ expected.\\\\  \textbf{2. What is the -3dB frequency of the op amp?}\\  2.006 KHz \\ \\\\  \textbf{3. What is the DC gain?}\\  75.21 dB\\ dB\\\\  \textbf{4. What is the unity-gain frequency?}\\  18.98 MHz\\ MHz\\\\  \textbf{5. What are the gain and phase margins?}\\  Gain Margin = 26.33 dB \\  Phase Margin = 180-60.477=119.5 degrees\\ degrees\\\\  \textbf{6. How the results agree with the calculations? You can for example make a comparison table to the final report.}\\\\  The results obtained are quite close to the calculations as evident from the following table.
