"WebYou could just make a voltage follower from an op-amp. A suitable op-amp follower might have a drift of +/-50~+/-500mV/minute with a 15pF cap on the input and an input of a volt or so. One problem is that the op-amp itself might have 5pF of input capacitance so you'd change the voltage by connecting it to the capacitor. " - How does internal resistance affect voltage
