Add the command ".options plotwinsize=0" to your schematic and run the simulation again. Select the result window and go to View FFT, take a screenshot of the FFT of vout. Note down the frequency and magnitude(in dB) of the first three peaks. What do the peaks in this plot represent? 6. Change the ac magnitude of the input to 50 mV and find the FFT of Vout. Note down the frequency and magnitude(in dB) of the first three peaks. How will you interpret two sets of data with different input amplitude? 7. Perform an AC sweep simulation to find the DC gain and bandwidth of the amplifier. Take a screenshot of the result. 8. In order to have larger small signal gain, we can increase either transconductance of the MOSFET or load resistance in the setup. In this section, we will increase the transconductance and explore its impact on gain and bandwidth. Write down the formula of ID and gm(in terms of ID and Vov). What values should you change to increase transconductance while keep operating points of the circuit fixed
