    Amplifier.Detection smoke.

    Hello, My name is Dragos.I am beginner in simulation S.P.I.C.E.. and I use the simulator Micro-CAP 12, to simulate an electric schematic. I want to simulate the phototransistor PIN InGaAs IG17-series and to monitor grafically the rectangular electrical impulse, at an amplitude of a few volts...

    Need help selecting photodetector

    The photodetector is to be used to detect green light from an optical fiber (emitted by fluorecein, about 500nm). I have tried using this detector, but with no readings. This diode has a response of about 0.25 A/W at 500nm. This is the amplifier I have used (OPA27GP): Is there a better...
