Hi buddypoor

how to achieve that in STB if having 2 loops?

In the STB setup, only one probe is allowed.

See Frank's answer in this thread.

Yes - I know this answer. But it does nort help at all because Frank just confirms that BOTH loops have to be opened at the same time.
But - if this not always possible (i.e. nested loops).

For example band gap, opamp o/p is prefect point to keep stb-probe. Could you tell me where to put the iprobe for this bandgap? http://kitmonisit.com/
