A transpolarizer is employed as a programmable capacitance divider. Two ferroelectric capacitors are coupled in series to form a common node and two extreme poles. The polarization of the two capacitors is set by grounding the two poles and then bringing them both up to VCC while impressing a voltage...http://www.google.es/patents/US4853893?utm_source=gb-gplus-sharePatente US4853893 - Data storage device and method of using a ferroelectric capacitance divider
