Hello...
I'm trying to solve a new amplifier problem with a BJT.
The circuit is attached and also a screenshot.
I think I have already found:
\(\displaystyle {R_{i}=\left [ \left ( R_{b1}\parallel R_{b2} \right ) + hie + \left ( hfe + 1 \right )\cdot \left ( R_{e} \parallel R_{Load}\right )\right ]}\)
But now I'm struggling to find Vi. Can anyone give a hand?
