An oscillator circuit having an amplifier and feedback loop multiplies a generated signal by appropriate selection of capacitance ratios in the feedback loop. In order to isolate this multiplied, high voltage signal, a voltage divider is used to isolate the high voltage portion from the input and output...http://www.google.fr/patents/US5457434?utm_source=gb-gplus-shareBrevet US5457434 - Integrated circuit oscillator with high voltage feedback network
