ABSTRACT:
A single pin oscillator which consists of first and second transistors (17, 18) whose collectors are connected, via respective collector resistances (19, 20), to the positive pole of a DC source U.sub.V and whose emitters are connected to the negative pole thereof via respective emitter resistances (21, 22). The collector of each transistor is connected to the base of the other transistor. A quartz crystal (12) or a series resonant circuit is connected to the emitter of one transistor (17) and parallel to the corresponding emitter resistance (21). A driver circuit (23) is provided for an oscillator voltage which can be coupled out to an external low-ohmic, highly capacitive load connected to the emitter of the other transistor (18) and parallel to the corresponding emitter resistance (22).
