ABSTRACT:
A quartz-crystal oscillator circuit substantially reduces the start-up time of the crystal oscillator circuit by utilizing a start-up time reduction circuit that adds additional gain to the crystal oscillator circuit during the start-up period, and removes the additional gain as the oscillator circuit nears steady state operation. Furthermore, the start-up time reduction circuit dynamically monitors the oscillation amplitude. If the build up of oscillation is interrupted, the additional gain will be re-applied.
