摘要： 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 (ε
r ) 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.

摘要： A method of manufacturing a pyroelectric unit which includes the steps of imparting a temperature change to pyroelectrically coupling particles dispersed between a pair of opposed electrodes (13, 14) applied by an electric field before the particles adhere to the electrode (13) when manufacturing a laminate of particles for a polycrystalline pyroelectric unit or composite pyroelectric unit, thereby forming a layer of pyroelectrically coupling particles on the electrode (13) so that the orientation of the pyroelectric axes is aligned in advance. This temperature change could be done by the steps of cooling the vicinity of the electrode (13) by evaporation from the surface of the dispersion liquid (12), thus lowering the temperature of the liquid as the particles approach the electrode (13). Thus, dipoles are induced on the particles, and the orientation of the polarity of the pyroelectric axes can be performed by the electric field between the electrode pair before the particles adhere to the electrode (13).
摘要翻译：一种热电单元的制造方法，其特征在于，包括以下步骤：在将颗粒粘附到所述电极（13）之前通过电场施加的一对相对电极（13,14）之间分散的热分解耦合的粒子赋予温度变化，层叠多晶热电单元或复合热电单元的颗粒，从而在电极（13）上形成热电耦合颗粒层，使得热电轴线的取向预先对准。该温度变化可以通过从分散液（12）的表面蒸发而冷却电极（13）的附近的步骤进行，从而当粒子接近电极（13）时降低液体的温度。因此，在颗粒上诱发偶极子，并且热电轴的极性的取向可以通过在颗粒粘附到电极（13）之前的电极对之间的电场来执行。
