Lecture #4 BJT AC Analysis
• The dc analysis of npn and pnp configurations is quite different in the sense that the currents will have opposite directions and the voltages opposite polarities. • However, for an ac analysis where the signal will progress between positive and negative values, the ac equivalent circuit will be the same. npn versus pnp J-601-4 l-a
