An embodiment of a method for measuring an RMS voltage of an arbitrary time-varying waveform includes: a) coupling said arbitrary time-varying waveform to said thermally sensitive device; b) decoupling said arbitrary time-varying waveform from said thermally sensitive device; c) coupling said thermally sensitive device to said controlled DC voltage source; d) measuring a current through said thermally sensitive device at least two points in time; e) determining a change in said current over said at least two points in time; f) if said current is increasing between said at least two points in time, then decrease said controlled DC voltage source responsive to determining that said current is increasing; g) if said current is decreasing between said at least two points in time, then increase said controlled DC voltage source responsive to determining that said current is decreasing; and h) repeating steps a)-g).
