Energy (U) vs. charge (Q) characteristics of ferroelectric capacitor. The navy, green, and red-colored curve represents the U vs. Q curve of dielectric capacitor, ferroelectric capacitor, and capacitance-matched capacitor (i.e., the capacitor which is composed as the series connection of dielectric and ferroelectric capacitor), respectively. By capacitance-matching, the total U vs. Q curve has single energy minimum region, and thereby the hysteresis of ferroelectric capacitor no longer exists
