The invention relates to electronic device having an operation temperature range, wherein the electronic device comprises a tunable capacitor (CST) comprising a first electrode (BE), a second electrode (TE), and a dielectric (FEL) arranged between the first electrode (BE) and the second electrode (TE). The dielectric (FEL) comprises dielectric material (FEL) having a value of a relative dielectric constant (&#x2208;) varying at least within the operation temperature range. The electronic device further comprises a temperature varying means (RES) being thermally coupled to the tunable capacitor for providing a temperature of the dielectric (FEL) causing a predetermined capacitance of the tunable capacitor (CST). The invention, which relies on the idea of varying temperature to vary a capacitance of a capacitor stack, provides an alternative tunable capacitor type for the known types. Advantageous embodiments feature high-tuning ratio, small device area, and stable capacitance value in case the temperature is well controlled. The invention further relates to a semiconductor device comprising the electronic device in accordance with the invention, to an electronic circuit comprising such electronic device, and to a method of manufacturing such electronic device.
