FSS Open Loop Gain
Yoichi, Peter, Jenne
Attached is the open loop transfer function of the FSS as of today with the common gain = 12dB and the fast gain = 16dB.
The UGF is only 250kHz. If we increase the common gain, the PC goes crazy. Exactly the same symptom as before I fixed the oscillating op-amp.
I wanted to check the cross over frequency but there is no excitation point in the fast path nor PC path. Therefore, it is not easy.
