PreAmp and polygon
Hi guys,
I have designed a mike amplifier based up on TL074 chip. The circuit layout uses ppolygon as well. Now I have got a question, I would like to know where to put the GROUND pin of the mike on the layout? Is it beeter to connect it to the polygon, or it is better to put it in star ground which I have used to connect a power amplifier to the current circuit? Thanks a lot? |
