Abstract
The present invention solves the gain, noise figure, and distortion problems of prior art thermal compensation circuits by incorporating a temperature-compensating circuit in the feedback loop of a transistor amplifier arrangement. Using this method, the insertion loss is reduced as the gain of the amplifier varies proportionately to the temperature. This method has a negligible effect on the noise figure and distortion, and the incremental cost is much lower than the conventional circuits. Furthermore, the present invention can be used in both single-ended or push-pull dual amplifier configurations.
