Question

Here is the way to decide the constant parameters: a (k?) and b (v) for the following problems: a is the average of your U ID first four digits; b is the summation of your U ID last four digits. For Example, here one student U number is U01774042, a = (0+1+7+7)/4=15/4 (k?); b = 4+0+4+2 = 10(v). 1. (65pts) Figure out the exact $V_D$ and $I_D$ for the circuit given below with $V_{DD} = b(v)$, R= a and assume that the diode has a current of 1 mA at the voltage of 0.7 (v). 2. (35pts) For the circuit below, it is required to figure out the value of the resistor $R_a$ that results in the transistor operating ($V_{BB}$= b (v), $V_{BE}$ = 0.7 (v), ? =100): a. In the active mode with $V_{CE}$ = 6 (v); b. At the edge of saturation; c. Deep in saturation with $\beta_{forced}$ =10. please don't use the (a) and (b) on the paper. use a=1.5k ohms and b(v)=24 volts. VDD should = b(v) and R=a thanks

use a=1.5k ohms and b(v)=24 volts.
VDD should = b(v)
and R=a
