Abstract
Disclosures of the present invention particularly describe oscillator circuit with temperature compensation function, consisting of a fully differential amplifier, a current mirror unit, a bias current supplying unit, a compensation unit, and a reference signal generating unit. A variety of experimental data have proved that, based on the normal operation of the compensation unit and the reference signal generating unit, an oscillation frequency of this oscillator circuit would be maintained at same level even if the ambient temperature continuously increases. Therefore, because the frequency drift due to temperature variation would not occur in the oscillator circuit of the present invention, the novel oscillator circuit is potential oscillator to replace the conventional oscillators applied in analog-to-digital convertors or time-to-digital convertors.
