Abstract

Initial start up conditions for an oscillator having an inductor and capacitor coupled as a frequency determining resonant circuit are established by current generators. The current levels correlate to the steady state operating levels of the oscillator. Switching elements are actuated so as to gate the oscillator into immediate steady state operation without start up transient distortion by reconfiguring the relationship of the current sources to the oscillator elements.
