Abstract
A crystal oscillator circuit which does not produce runt pulses when the oscillator is turned on or off. The circuit includes a crystal oscillator, an integrator which integrates the energy in a plurality of pulses, a threshold circuit which is active when the output of the integrator reaches a pre-specified threshold and gating circuits which gate the output of the crystal oscillator to the output terminal only when the threshold circuit has reached the specified threshold.
