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.
