Hello!
I am working as a researcher in physics and need to transform a 0 to 10 V signal into a signal from -100 to 100 V. As I am unsure what the best solution for this would be I hope this is the correct forum to ask this question! So far I have only worked with low voltage circuits and I know little to nothing about higher voltages.
I am using the high voltages to control the gate electrode of graphene FETs, which requires voltages between -100 V and 100 V but no current will flow (i.e., I only need to source like a few uA at most due to external leakages). My testing equipment can only output 0 to 10 V. Ideally, I'd like to have a box that simply multiplies the voltage by 10 or -10 depending on a switch, but I am unsure if such DC-DC converters exist. So: 0V => 0V, 1V => 10V, 10 V => 100 V and a 'voltage inverter'. Is this possible with a DCDC converter, or do I need to get a high voltage power supply (potentially noisy/costly?) and use a HV opamp? It is important that there is very little noise on the signal (e.g. no 50 Hz noise).
I hope this is clear!
Cheers,
Bart
