ABSTRACT:
An analog front end device with temperature compensation is provided. The analog front end device comprises a bandgap voltage reference circuit, a clock generator, a temperature compensation circuit, one to three identical converting circuits and a Sync-on-Green circuit. The temperature compensation circuit is adapted to sense the temperature variations of the analog front end device and dynamically compensate the bandgap voltage reference circuit, the clock generator and the Sync-on-Green circuit as the temperature varies, which thereby controls the thermal drift in the analog front end device.
