3. An npn silicon (Er = 11.9) bipolar transistor (shown in Fig. 1) at T = 300K has uniform dopings of 61a596aec1a6c.jpg. The transistor is operating in the inverse- active mode with 61a5972074c66.jpg = 0.565 V. (a) Determine the minority carrier concentrations at x = xB and x" = 0(b) If the metallurgical base width is 1.1 um, determine the neutral base width (20%)
