R 1 R 3 R 4 C 2 C B 1 C B 2 C 1 V CC v L v S R L R E R 2 Analyze using both circuit theory and feedback theory how bootstrapping can increase the input impedance. To aid you in your analysis, follow the steps given below. 1) Draw the smallsignal, a.c. equivalent circuit at midfrequency for both circuits and compare their input impedance. 2) Draw the smallsignal a.c. equivalent circuit at midfrequency for both circuits without feedback and compare R i . 3) Determine β v and calculate the closed loop R if for both circuits....
