Abstract

An oscillator for producing an oscillating signal with reduced harmonics includes an oscillator stage coupled to an output stage having a relatively fast switching speed yet producing an oscillating signal having relatively slow rise and fall times so that the harmonics output by the oscillator are reduced. In one embodiment, the oscillator includes an output stage having low power Schottky circuitry, and in a second embodiment, the output stage includes a capacitor connected across the output stage of the oscillator to increase the rise and fall times of the oscillator.
