ABSTRACT:
An electrical or electronic circuit having at least one variable capacitor device connected in parallel relationship in the circuit by at least a pair of electrodes. The improvement constitutes the capacitor device being in the form of a silicon dioxide film derived from the oxidation of a hydrogen silsequioxane resin. The silicon dioxide film is characterized by a non-linear substantially symmetrical jV curve which includes a threshold voltage at which the silicon dioxide film undergoes a reversible transition from insulating to conducting. The jV curve further includes a regime of negative differential resistance in which an increase in the voltage applied to the silicon dioxide film above the threshold voltage causes a decrease of the current.
