A VCO buffer circuit comprising a first loading means receiving a first signal for loading the VCO at a first input node; a second loading means receiving a second signal for loading the VCO at a second input node; a third loading means coupled to said first loading means for loading the VCO at third input node to thereby balance a load distribution on three nodes of VCO. At least three current controlling means are coupled to each other to form a symmetrical configuration and receive input signals from said first and second loading means for minimizing variations in the oscillation frequency of the VCO. A buffering means is connected to the output of the controlling means for buffering the output of the current controlling means.
