1.計算題(10分) Figure P1 shows the BJT amplifier with a current gain βof BJT is 100, thermal voltage VT = 25 mV and collector current63070f3f63268.jpg. Assume that when 63070f5d3afc5.jpg is 0.7 V, lc is 1 mA. When Vc is -5 V, design RE and Rcto make Ic equal to 4 mA. Note the answer must be rounded to two decimal places. (RE與Rc各5 分)
