Abstract
The oscillation generator includes an oscillator circuit, a push-pull amplifier with inductive positive feedback connected in the circuit, a piezoceramic atomizer vibrator element, and a load-dependent regenerative feedback coupling connected to the circuit. The coupling is in the form of a tunable frequency-selective sensor having outputs connected to the inputs of the amplifier.
