An oscillator for use within an implantable medical device is provided. The oscillator includes a resonator and a first switch coupled to a first resistive network. The first resistive network provides a first electrical path through the first switch and a second electrical path not going through the switch. The oscillator additionally includes a second switch coupled to a second resistive network. The second resistive network provides a third electrical path through the second switch and a fourth electrical path not going through the switch. Furthermore, the oscillator includes a transistor, the base terminal coupled with the first resistive network and the resonator and the emitter terminal coupled to the fourth resistor. The second electrical path with the first switch opened has a substantially higher resistance than the first electrical path when the first switch is closed. In addition, the fourth electrical path with the second switch opened has a substantially higher resistance than the third electrical path when the second switch is closed.
