Abstract:
A four-phase oscillator includes, a first oscillator configured to output a first differential signal, a second oscillator configured to output a second differential signal shifted in phase with respect to the first differential signal by 90 or −90 degrees, and a control circuit. The first oscillator includes a first tail current source and a second tail current source. The second oscillator includes a third tail current source and a fourth tail current source. The control circuit changes the frequency of the first and second differential signals by controlling at least one of a difference between a first current value supplied from the first tail current source and a third current value supplied from the third tail current source and a difference between a second current value supplied from the second tail current source and a fourth current value supplied from the fourth tail current source.

Claim (Index 5):
The four-phase oscillator according to  claim 4 , wherein when the control circuit reduces the frequency of the first and second differential signals by performing at least one of setting the first current value higher than the second current value and setting the third current value higher than the fourth current value and increases the frequency of the first and second differential signals by performing at least one of setting the second current value higher than the first current value and setting the fourth current value higher than the third current value.
