Lets say I have some 10MHz (+-0.001HZ) precision reference signal that I want to convert to quite a precise 10V Voltage reference. Unfortunately I don’t have anything like a josephson junction available (or ten thousands…), and when I spend too much money my wife will kill me.
Looking around for semiconductor voltage references it seems that the highest precision is around 0.01% initial accuracy (the quantum volt doesn’t seem to be ready yet), so to be much better than them, I would like to target, say, 0.0001% accuracy.
Looking into existing precision frequency to voltage converters, although having nice linearity components, even if they were sufficient, the devices would still require some reference calibration, which is exactly what I want to avoid.
So is there any technology that fits this gap? That is, intrinsic high precision frequency to voltage conversion without the need for calibration or laboratory grade equipment (and prices)?
