Hi
In the circuit below, if I feed the circuit with +30V, will Zener D3 force the reference of +30V supply to be -13V instead of 0V? This would be like a negative reference instead of a negative voltage, right? I'm confused because I don't believe I'm creating a negative voltage with this setup. Is this setup good to power low power dual supply op amps?
