Sinusoidal oscillator with instant start-up.

摘要

Initial start up conditions for an oscillator (12-16) having an inductor (12) and capacitor (14) coupled as a frequency determining resonant circuit are established by current generators (18-40). The current levels correlate to the steady state operating levels of the oscillator. Switching elements (41-44) 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.
