  • Phase-locked loop circuit
    Patent number: 7332972
    Abstract: Phase locked loop circuit (105) having a double entry VCO (158) and two independent charge pumps (171, 172), each connected with one of the entries of the VCO. Each of the VCO entries has a different gain coefficient, thereby allowing a better optimisation and control of the device bandwidth and a reduced phase noise. Can be employed in radio transmitters and/or receivers and allows simultaneous and precise FM modulation both inside and outside the PLL bandwidth.
