Abstract
A voltage supply and a method for calibrating the voltage supply are provided. The voltage supply is for providing a reference voltage to supply a voltage to at least one electrode. The voltage supply comprises: an ultra-stable DC voltage source, an accurate DC voltage source, a tuning unit, a comparator, and a control unit. An ultra-stable voltage is applied to the tuning unit, which is provided based on a supplied voltage of the ultra-stable DC voltage source. The tuning unit provides an output voltage. A voltage based on the output voltage of the tuning unit is compared by the comparator with an accurate voltage. The accurate voltage is provided based on a supplied voltage of the accurate DC voltage source. The comparator provides a signal resulting from the comparison to the control unit, wherein the control unit is tuning the tuning unit during a tuning period according to the signal provided by the comparator to minimize the absolute difference between the voltage based on the output voltage of the tuning unit and the accurate voltage. The reference voltage of the voltage supply is provided based on the output voltage of the tuning unit after the tuning period.
