| 1. A method of adjusting a DC power supply output, the method comprising:
comparing a voltage at a negative terminal input to a device with a target voltage at the negative terminal input to obtain
an offset voltage;
producing an error amplifier reference voltage based on the offset voltage and a target value of a voltage on a positive terminal
input to the device;
comparing the error amplifier reference voltage with a voltage of the positive terminal to the device to produce an error
voltage; and
adjusting a positive output voltage of the power supply to the positive terminal based on the error voltage so as to maintain
an intended voltage differential between the negative terminal input and the positive terminal input.
