Abstract
Official abstract text for this publication.
The invention provides a temperature detecting apparatus, a switch capacitor apparatus and a voltage integrating circuit. The voltage integrating circuit includes an operating amplifier, a capacitor and a current source. The operating amplifier has a positive input end, a negative input end and an output end. The output end of the operating amplifier generates an output voltage, and the positive input end receives a reference voltage. The capacitor is coupled between the output end and the negative input end of the operating amplifier. The current source is coupled to the output end of the operating amplifier. The current source draws a replica current from the capacitor, and a current level of the replica current is determined according to a current level of a current flowing to the negative input end of the operating amplifier.
