BIPOLAR TRANSISTOR HETEROJUNCTION INSENSITIVE TO VARIATION OF OUTSIDE TEMPERATURE AND ASSOCIATED INTEGRATED CIRCUIT.

摘要

The present invention relates to the stabilization of the behavior, particularly in the case of microwave applications, analog or digital, as a function of the external operating temperature of the heterojunction bipolar transistor. It also relates to an associated integrated circuit. BR/ According to the invention, the transistor (6) is polarized (DC) continuously by its base by means of a stabilizing resistor (5) while the signal to be amplified (RF) is transmitted to the base by via a connecting capacitor (4). BR/ The transistor of the invention is compensated directly internally during its manufacture. The integrated circuits that contain it do not need external temperature control devices. Neither do you need to account for ambient temperature variations when designing them. / P
