ground of DC bias supply

jarthel · 30th May 2007, 11:58 PM

some designs require a positive/negative bias DC supply. Do you connect the ground of these supplies to the main B+ ground?

thank you.

The simple answer is yes. All of the power supplies need a reference point. Normally this is the negative output of the power supply.
