Temperature compensator of television receiver

Abstract

Abstract PURPOSE: To allow this device to respond to the self-heated temperature change of an integrated circuit by arranging a thermistor so as to be made substantially close to the control input temperature of an integrated circuit amplifier which should control the thermistor. CONSTITUTION: The DC level of a luminance signal is changed according to surrounding temperature change and self-heating type temperature change. A thermistor 170 is attached physically close to the control input terminal of an integrated circuit IC 100, and electrically connected with a luminance input terminal in parallel to the movable arm of a control potentiometer 160 so that this influence can be compensated. When temperature sensed by the thermistor 170 is increased, a control voltage supplied by the movable arm of the control potentiometer 160 is decreased.
