Amplifier Frequency Response - Ken Kuhn's

Amplifier Frequency ResponseAn example problemThe transistor circuit in Figure 7 will be analyzed for low and high cutoff frequencies.The summary results from bias analysis and AC analysis are shown. We use the resultsfrom AC analysis to do frequency response analysis. Note that a significant value forC BC has been inserted to arbitrarily lower the high frequency bandwidth.Figure 7: Example circuitV CC = 12V, R S = 1K, R B 1 = 150K, R B 2 = 22K, RE = 1.5K, R C = 10K, R L = 10K,C B = 1 uF, CE = 100 uF, CC = 0.1 uF, C BC = 1 nF, CL = 1 nF,Not shown are: C BE = 30 pF, Cin_stray = 25 pF, Co stray = 20 pFSummary bias and AC analysis using B = 150 and V BE = 0.65V BB = 1.53 VR B = 19.2 KI E = 541 uAI C = 537 uAV C = 6.6 Vr e = 48 ohmsrbt = 7.25KR in = 5.26 KR o = 10KAv = 207Avl = 1038
