摘要:
An electrical oscillator circuit (301, 302) comprising: a resonator (303) comprised in the first subcircuit (301); and an active device (309) comprised in the second subcircuit (302) connected to energize the resonator (303) to provide an oscillating electrical signal transmitted as a differential signal via electrical conductors (306, 307) to the second subcircuit (302). The oscillator is characterized in that the second subcircuit (302) comprises means (311, 312, 313, 314) for receiving the differential signal transmitted via the electrical conductors (306, 307) and converting the differential signal to a single-ended signal with reference to the signal ground reference (G2) of the second subcircuit (302). Thereby a noise robust oscillator signal is provided with the use of very few components. Particularly suitable for oscillators embodied in an integrated circuit with the resonator mounted on a printed circuit board, PCB. And an integrated circuit.
