Abstract
A Global positioning system and integrated circuit, and a method for starting an associated quartz oscillator with an oscillator circuit that has terminals for a quartz crystal in order to generate a reference signal, and with a status circuit connected to the oscillator circuit, wherein the status circuit has first means for producing a constant operating current of an operating state and a constant starting current of a starting state for the oscillator circuit, the status circuit has second means for producing a quantity dependent on the amplitude of the reference signal, the status circuit has a comparator for comparing the quantity to a switch-on threshold value, and the status circuit has a current switch that is connected to the comparator in such a manner that when the switch-on threshold is exceeded by the quantity, the current switch switches from the starting current to the operating current.
