Question

3.5 4 marks) Table of measurements in Table-A (see previous page) provides Rc two sets of measurements characterizing the Ic versus VCE behaviour of a BJT in circuit of Fig. B, under two different circuit conditions (assume that B and all the environmental conditions remain unaltered between the measurements). lc RE Fig. B: Circuit for Problem 3.5 a) Interpreting both the measurement data in Table-A and graph in Fig. A, i) Determine the value of the Vcc used in this circuit: i) Determine the value of the load resistance that is used in the dircuit. Show the calculations: ii) Determine the small signal output resistance of the BJT.Show the calculations: v) Determine the operating point of the BJT from, Measurement Set-1: Q1:し J - Measurement Set-204 L v) Did the operating point shift during the two measurements (Yes/No): vi) If it shifted during from Measurement-1ぅぅMeasurement-2, to which region of the BT Characteristics, the Q point tended to shift towards: fill in the names the regions (Cut-off/Saturation/Active) below: from region (Q1) towards A (4 marks) The below table provides two sets of measurements characterizing the lc versus VCE behavior of a BIT under two different circuit conditions.
