Abstract
The present invention relates to a device for generating an alternating voltage difference between a first and second reference potential. The device comprises: an oscillator electrically referenced to the first reference potential; and a voltage follower/amplifier device electrically referenced to the second reference potential and having an input connected to the oscillator and an output connected to the first reference potential such that it can impose an alternating voltage difference, which depends on the signal generated by the oscillator, between said first and second reference potentials. The invention also relates to a system that uses the device and to a method for generating an alternating voltage difference between a first and second reference potential.
