A radio transceiver of a telecommunication system is provided, the radio transceiver including an integrated circuit comprising a phase locked loop, the phase locked loop including a voltage controlled oscillator, a detector unit, and a control unit. The spurious charge accumulated in the charge source in the control unit is conducted to the ground between two successive current pulses generated by the charge source, thus improving the stability and spectral quality of the output signal of the phase locked loop.
