    Hi ,

    1.I want to design a Colpitts crystal oscillator , with a square wave output.

    2.I want to design a Voltage Controlled Oscillator (colpittes type , that generates a square wave output.

    Reason , I am trying to design a Phase Locked Loop , that will give a stable frequency output of 4MHz.
    But I need a crystal oscillator as a reference to my PLL and a VCO as part of the PLL circuit.

    any suggestions , please.
