发明名称 Oscillator arrangement having increased EMI robustness
摘要 An oscillator arrangement having a resonator and a drive circuit which is connected to a connecting terminal of the oscillator is disclosed. In one embodiment, the oscillator includes a current source circuit is connected between a terminal for a first supply potential and the connecting terminal of the resonator and supplies the connecting terminal with a current source current which varies periodically at an oscillator frequency. A current sink circuit is connected between the connecting terminal of the resonator and a second supply potential, where the current sink circuit draws a current sink current from the connecting terminal, said current sink current varying periodically at the oscillator frequency and being negatively fed back to the current source current.
