Gain loop formula - Click HERE for Original Thread

Hi,

In the trade …>Solid State>Phase-Gain plot, will this oscillate? references are reported which state gain loop of a circuit is given by the following:
1/G= (1/Gv+1/Gi)

where Gv and Gi are voltage and current gain loop respectively.

Can anyone give me references ( possibly on the web) about how the above formula is mathematically derived?

Thanks in advance

Federico
