Abstract
An oscillator provides output signals over a range of oscillating frequencies includes an resonant circuit, at least one active circuit device operatively coupled to the resonant circuit to supply energy to the resonant circuit, and at least one unidirectional device coupled to the active circuit device. The unidirectional device permits current to flow between the active circuit device and the resonant circuit when the active circuit device adds energy to the resonant circuit, and impedes a drain of energy from the resonant circuit due to increased output signal amplitude.
