The following transfer characteristic and output characteristic curves for an NPN BJT were obtained from a curve tracer. The measurements were made at a temperature of 300K. The transfer characteristic was measured with collector-emitter voltage VCB=12V. The base current step size was set to 20μA to obtain the output characteristic curves. Thus, the lowest output characteristic curve is for base current IB= 0μA and the highest curve is for base current IB= 100μA You can open the images in a new tab to enlarge them. In finding the parameters for this question, it is a good idea to calculate them using multiple points read from the curves, then throw out any outliers and take the average. From the measured data, determine the Early voltage VA for the transistor. Enter your answer in volts to the nearest volt From the measured data, determine β0 for the transistor. Enter your answer to the nearest tenth. From the measured data, determine IS0 for the transistor. Enter your answer in femtoamperes (femto = 1e-15) to the nearest tenth.
