  • Oscillator circuit having trimmable capacitor array receiving a reference current
    Patent number: 6326859
    Abstract: An oscillator circuit includes a current generator which supplies current to input terminals of capacitors in a trimmable capacitor array. The input terminals of the capacitors are held at a relatively constant voltage, and thus all of the current from the current generator passes through the desired capacitors of the capacitor array, thus minimizing the effect of parasitic capacitance.
