Hi all

can anyone help with reasoning. When designing a 2 stage BJT amplifier with a pnp transistor. there is a bypass capacitor across Re one may connect to Vcc for pnp transistor of which the Vcc becomes ground in AC model. If one decide to connect that capacitor to ground instead of Vcc what effect may it bring when you take a circuit to AC model.

Make the AC model of the transistor and see where it is connected. Then analyze the circuit to see the effect.
