description A relaxation oscillator for generating an oscillator output signal having a predetermined frequency. The relaxation oscillator includes an interleaved charge pump for providing a restoring charge to an integrator in response to at least one charge pump control signal. The relaxation oscillator further includes an integrator having an integrator input connected to the current summing node. The integrator is adapted to produce an integrator output signal having the predetermined frequency at an integrator output. A comparator having an input connected to the integrator output is adapted to generate the oscillator output signal having the predetermined frequency in response to the integrator output signal.
