Hi all,
In terms of applying the hybrid-pi model for a pnp transistor, is there anything I should be aware of compared to applying this model to npn. ie) Should the vbe be a -ive voltage ( I don't think so )? Should I expect the calculated currents, ie, ib, and ic to have negative signs?

Thanks, Michael
