  • Precision relaxation oscillator integrated circuit with temperature compensation
    Patent number: 6020792
    Abstract: A precision relaxation oscillator with temperature compensation produces a stable clock frequency over wide variations of ambient temperature. The invention has a oscillation generator and two independent current generators. The outputs of the two programmable, independent current generators are combined to provide a capacitor charging current which is independent of temperature. The precision relaxation oscillator with temperature compensation is implemented on a single, monolithic integrated circuit.
