Abstract: A varactor is provided. A substrate includes a first surface, a second surface and a first opening and a second opening in the substrate. A conductive material is filling the first and second openings, to form a first through-wafer via (TWV) and a second through-wafer via. A first capacitor is coupled between the first through-wafer via and a first terminal. A second capacitor is coupled between the second through-wafer via and a second terminal. A capacitance of a depletion-region capacitor between the first through-wafer via and the second through-wafer via is determined by a bias voltage applied to the first through-wafer via and the second through-wafer via.

Abstract: A high-frequency component test device including a test key and a test module is provided. The test key includes a front-level key and a back-level key which are arranged symmetrically and have the same electrical length and characteristic impedance. The test module is used to measure an S parameter of the front-level key and the back-level key connected directly and an S parameter of a structure where a device under test (DUT) is added between the front-level key and the back-level key. The test module performs S parameter calculation in the frequency domain and converts the S parameter into an ABCD parameter matrix, and then obtains an ABCD parameter of a de-embedded DUT using a matrix root-opening operation and an inverse matrix operation.

Abstract: A neural circuit is provided. The neural circuit includes a neural array. The neural array includes a plurality of semiconductor components. Each of the semiconductor components stores a weighting value to generate a corresponding output current or a corresponding equivalent resistance. The neural array receives a plurality of input signals to control the semiconductor components in the neural array and respectively generates the output currents or changes the equivalent resistances. Since the semiconductor components are coupled to each other, output of the neural array may generate a summation current or a summation equivalent resistance related to the input signals and a weighting condition, so that a computing result exhibits high performance.
