Analysis of Shunt Shunt Circuit
I am having trouble computing the closed loop gain of the circuit below:
It seems clear that this configuration is a Shunt Voltage but I just can't figure a way of computing the feedback factor and the open loop gain.I know the gain has to be a transimpedance and so it can't just be the transistor gain beta.
Can someone please help me prove that
$$ A = -\beta R_c $$
$$ k = -\frac{1}{R_f} $$
$$ A_{cl} = \frac{\beta R_c R_f}{R_f + \beta R_c} $$
