Abstract
Capacitors whose capacitance is a function of voltage can be made using commercially available barium strontium titanate ceramics. Such nonlinear capacitors can be used as controllable impedances to form a dielectric amplifier. Using nonresonant circuits without transformers or feedback, amplifiers have been tested and found to give a large power amplification. but with an output voltage less than the input voltage. Using resonant circuits a voltage amplification of four has been obtained with the same materials.
