Abstract:
1. A temperature compensation device for an automatic gain control loop in a receiver of a mobile communication terminal, comprising: a thermistor having a resistance varying with temperature to vary an output voltage; an analog/digital converter for converting the output voltage from said thermistor into a digital signal; and a temperature compensator for outputting a temperature compensation value in response to the digital signal based on a specific temperature variation, wherein said temperature compensator has a plurality of gain change threshold values corresponding respectively to various temperature variations, said temperature compensator outputting one of the gain change threshold values corresponding to said specific temperature variation as said temperature compensation value upon receiving said digital signal based on said specific temperature variation, and said temperature compensator is adapted to provide said gain change threshold value corresponding to said specific temperature variation to a gain determiner. said gain determiner determining a gain of each component of said receiver.
