MoodleEE 206 Class, keeping the file size less than 1 MB. Your file name should be your_roll_number_HA5(for example, 100102001_HA5.pdf). Problem 1The gm1= gm2= 120 μS. Assume R1= R2= R3= 1 K
. C1= 100 pF and neglect all other capacitors. Channel length modulation parameter
= 0. (a) Identify the type of feedback
(b)Discuss what happens to input/output impedances beforeand after feedback is applied
(c)Estimate the numerical values closed-loop voltage gain for very low frequencies and very high frequencies
(d)Discuss the steps you have taken to arrive at the answers. Problem 2The gm1= gm2= gm3= gm4= 120 μS. Assume R1= R2= 1 K
. Channel length modulation parameter = 0.
