Can Voltage Be Negative? Understanding Negative Voltage

WebWhen we integrated all negative and positive amplitude/power data in five EEG bands (delta, theta, alpha, beta, gamma), a few relative power results became huge (i.e., 440%(44.44) or even over 1000%). WebIf OUT is grounded, the desired negative voltage can be achieved by selecting R3 and R4 such that: Vout- = - Vref * (1 + R4/R3) - Iadj * R4 To my knowledge of your application, I do not believe there is anything wrong with operating the regulator in this configuration since, as you have pointed out, there is no ground reference pin.
