Abstract: The oscillator comprises a plurality of differential amplication stages (10,12,14,16) each arranged to introduce a phase shift between its differential input signal and its differential output signal such that the total phase shift introduced by the stages is 360 o . In this way an oscillating signal is produced at the output of each stage. Because each stage receives and supplies difference signals, any changes in the power supply of the stages affect both inputs or outputs in the same way so that the effect on the differential signal is minimal. The circuit thus provides a reduction of the effect of power supply noise. The oscillator may be used for instance in a N-PLL-circuit.
