Abstract: The invention relates to an electronic apparatus comprising at least one transistor having a control terminal and an intrinsic capacitance junction with a variable value as a function of the temperature, said transistor being associated with a compensation device for compensating the effects of the variation of said intrinsic capacitance junction. To this end, the electronic apparatus is characterized in that said compensation device comprises a combination of means behaving as a variable capacitance, said variable capacitance having such a variation as a function of the temperature that it compensates said effects, said variable capacitance being connected to said intrinsic capacitance.

Abstract: The present invention relates to a circuit intended to generate a negative conductance NG between two connection terminals A and B, including a first and a second transistor T1 and T2 connected as a differential pair between said connection terminals A and B.
