Abstract
An oscillator for generating oscillation signals. The oscillation signals are initiated in response to an applied start signal and begin at a fixed predetermined phase. Hence, the oscillator is suitable for use in phase dependent timing systems to inhibit phase jitter which could otherwise occur. The oscillator includes an inverting amplifier and phase shifting feedback network for establishing and maintaining oscillations. The phase shifting feedback network includes a series coupled coil between the output and input of the inverting amplifier. A bias circuit is included for injecting direct current through the coil when oscillation is inhibited to generate a direct current magnetic field in the coil. The magnetic field ensures that, in response to the start signal, the oscillation signals begin at said fixed phase.
