The cascode CS amplifier below has 3 poles with frequencies stated as: fp1 = 100 kHz, fp2 = 100 MHz, fp3 = 10 GHz. The DC gain of this structure is |Av| = 100 (linear not dB). Considering the load capacitance, CL, is 4 orders of magnitude bigger than the parasitic capacitances of the transistors, answer the following questions: 1) What is the approximate bandwidth of the amplifier? 2) Which of the poles is corresponds with the fp1 pole? Is it PIN, PX, or POUT? Why? 3) Sketch the bode plot (amplitude and phase) of the gain of this amplifier up to 100 GHz. Indicate the gain corresponding to each pole, the slope of the lines, and the drop in phase after each pole. 4) Find the approximate unity gain frequency of the amplifier. 5) Find the approximate phase margin of the amplifi
