Here's what I know. The circuit is measuring the current of a laser diode using a current mirror. for the analysis to make things easy assume 100ma is entering the system. I get confused about how the currents run through the circuit. I'm pretty sure the first op amp has a gain of -3.0. besides this I have no idea how to go about solving the gain of the second op amp etc. This all interfaces to a hotmux data logger that can handle a voltage of 0-50mv.
I hope this is enough info. also Stepping through this would be fantastic.
Thank you
