Nanopositioning techniques currently applied to characterize physical
properties of materials interesting for applications at the microscopic scale
rely on high-voltage electronic control circuits that should have the lowest
possible noise level. Here we introduce a simple, flexible, and custom-built
power supply circuit that can provide +375\,V with a noise level below 10\,ppm.
The flexibility of the circuit comes from its topology based on discrete MOSFET
components that can be suitable replaced in order to change the polarity as
well as the output voltage and current.Comment: 3 pages, 2 figure
