Note on Diode Circuit: 3-1 Full-wave rectifier How to identify a diode? Current flows from the anode (positive, p side) to the cathode (negative, n side), but not the other way around. To identify a diode, the black line on the package represents the cathode side of a diode. In PSPICE simulation, to probe a voltage drop across two points, one can use the V+ V- probe. In running a time transient RC circuit simulation, one would like to skip the initial time (t=0s) and instead look at the steady state result (the result one would see in the oscilloscope). PSPICE can show the simulation in any time frame defined by the user.

Unformatted text preview: RC circuit. 3-2 Photodiode Amplifier Pinout of photodiode (BPW77) used: Our photodiode is actually a Bipolar Junction Transistor (BJT), which consists of a collector (C), a base (B) and an emitter (E) For a photo-diode amplifier setup: Therefore the Base (B) will be placed in a ground, while the emitter (E) section is placed into the op-amp circuit. For deriving the relationship between V out and I in , assuming the photodiode has a additional current source as shown: where two currents Iin is flowing from V- to the current source, another is flowing out of Vout....
