Temperature compensation device for automatic gain control loop

摘要

A temperature compensation device for an automatic gain control loop in a receiver of a mobile communication terminal is disclosed. The temperature compensation device comprises a thermistor having a resistance varying with temperature to vary its output voltage, an analog/digital converter for converting the output voltage from the thermistor into a digital signal, and a temperature compensator for outputting a temperature compensation value in response to a digital signal based on a specific temperature variation from the analog/digital converter.
