Send the moderators a message and we can unblock it as soon as possible. Since phototransistors have amplification built into their semiconductor structure, we don’t need an op-amp-based transimpedance amplifier (TIA). If the problem is truly an engineering problem, we'll allow it, but fixing your laptop or a cracked LCD screen doesn't qualify.ĭo not post Discord links, surveys, or job postings (with the exception of the monthly job post).Ĭan't find your submission? It was probably caught by reddit's spam filters. As with photodiodes, the goal with phototransistors is to produce a usable output voltage from the light-generated current. Tech support help can be found in /r/gadgets. If you have specific, targeted questions regarding homework, we will help you out only if you have provided some beginning work. Power, electronics, electromagnetics, semiconductors, software engineering, embedded systems - all topics relevant to this field, professional or academic.
