Polarização e estabukizacao com Ie constante com transiator PNP. Aplicando Kirc pra tensão: Na entrada Vcc= Vrb1+Vrb2. Na saida Vcc= Vrc+Vce+Vre. Ou Vcc= Ic.Rc+Vce+Ie.re. A análise pra correntes: Ie= Ib+Ic, ib1= ib+Ib2, podemos considerar Ib2= 10. Ib, como obs podemos aplicar B= Ic/Ib...then Ic= B.Ib e Ib= Ic/B.

Vcc= Ib1.Rb1+Ib2.Rb2 ( kirchhoff )
