Temperature compensation device and electronic apparatus comprising such a device

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. The invention is particularly advantageous for compensating the frequency drift of a voltage-controlled oscillator.
