Hi all, i have been tasked to design a Transimpedance amplifier using BJT'S, In this case a CE - CC stage amplifier. I have shown the circuit and H parameter below,
Im struggling in the derivation of the gain which is needed to verify my multisim results. If anyone could give any support i would greatly appreciate it.
I am particularly struggling with including the Feedback resistor, the value has been calculated in order to suit my bandwidth of 1Mhz.

If it's a little lower than 50k I'd just believe the sim and move on :p

The circuit for the CC output stage doesn’t look right: the input impedance will be higher than that of the CE input stage, but you have them both at hie.
I would start with transistor models based on transconductance, rather than current gain.

Is this the place for college kids to come get help with their homework now? :-DD
