<p>The oscillator (500) has loop systems (502) including a main phase shifting device (506) provided with a main phase shifting cell (306) for phase shifting of control signals at an adjustable phase shifting value. Each cell defines a phase shifting level. An adjusting unit adjusts phase shift realized by each cell by multiplication and summing of the control signals in quadrature, where one of the quadrature control signals is a main signal and the other quadrature control signal is a secondary signal for each cell of the loop systems.</p> |
