Abstract

An extra symmetry is introduced into resonant circuits in order to make the location of voltage nodes (+Vdc, -Vdc) of the resonant waveform stationary. These stationary voltage nodes (+Vdc, -Vdc) are then used as the contact points of the bias circuitry to the resonant structure. Connecting the bias circuitry to the voltage nodes insures no resonant energy escapes the resonator into the bias circuitry thus ensuring no degradation of the resonant quality factor ('Q') and no interfering energy in the bias circuitry.
