It is shown how some photovoltaic MOSFET drivers can be used for the realisation of a low noise, programmable voltage source, with a dynamic range that can easily exceed several tens of volts starting from standard ± 12 V power supplies. Such a source can be useful in the investigation of the electrical properties, and particularly noise properties, of organic thin film transistors on plastic substrates, since relatively large gate voltage sweeps are required in order to obtain a significant change in the conduction properties of the channel.
