Title: OSCILLATOR CIRCUIT
Abstract:
An oscillator circuit includes a current generator (4) which supplies current to input terminals of capacitors (C0, C1) 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 effetct of parasitic capacitance.
