(a) Use Table 10.4 Conversion of BJT high-frequency modeling parameters into find Cu and C1 (10 points)your textbook (b) Find the low frequency poles. What is the dominant pole frequency, and which capacitor dominates the low frequency pole location?(20 points) (c) Draw the high frequency amplifier model with Cụ and Cr . Find the high frequency cutoff using Cu and Cz . You may choose to use the small signal hybrid-n model of the amp to find the cut-off frequency. Or you can apply Miller's theorem and calculate the cutoff frequency. Or, use a virtual BJT, insert your value of Br for the transistors, and draw inMultiSim Cu connected between base and collector, and Cn connected between base and emitter. Then simulate the amp to find its high cutoff frequency. (30 points) The amplifier BJTS in the circuit below, have the following specifications shown has the following specifications:BF = 220, VA = 350 V, rb = 0.13 Q. CJE=27 pF, VJE = yF 0.75,MJE = m = 0.33, TF = 0.325 ns, fr = 490 MHz, CJC =9.12 pF, CJS =0 pF.
