Hi all :) I need some help with the concept of parasitic capacitance. I'm currently doing some analysis on a basic tuned transistor circuit. I know the LCR portion of the circuit is there to remove parasitic capacitance. The only problem I'm having is I don't exactly know what parasitic capacitance is. As far as I can tell, it's a problem with the transistor at high frequencies which causes it to cut off. Can anyone please elaborate or correct me? I can post a circuit diagram if needed. Thanks.
