Project 2207Figure 1 . SchematicDesign R1 and R2 so that the collector on-line(prenominal) of Q1 is closely 2mA . The modern by dint of R1 and R2 should be 10 of the collector current as a rough rule13 .55 kApplying again Kirchoffs potency justness , the unification of the electric potentials across R1 and R2 is equal to V2 9 VIR1 R1 IR2 R2 V2Since the current flux through R1 is the sum of the current that flows through R2 and the base-emitter current IB IC /ss25 ?C we can solve for R2R1 29 .

95 kCalculate the values of the morsel s ignal equivalent circuit of Q1 and determine the forward voltage transfer function (VS to VOUT ) including all poles and zerosFigure 2 . re simulation equivalent circuitWe solve for re1re1 13We solve for ro1 from hoe 5 umhoro1 cc kawzhimf0-RTtftzshTtz-istance divided by the Since VOUT isAnd since i1 ib ss we get the next transfer functionIf frequence is very high then Xc is almost zeroSimplifying the in a higher place equation by substituting the hobby variablesWe get the following transfer function...If you want to get a full essay, invite it on our website: OrderEssay.net
