US10644657B1 Multi-band digital compensator for a non-linear system
A pre-distorter that both accurately compensates for the non-linearities of a radio frequency transmit chain, and that imposes as few computation requirements in terms of arithmetic operations, uses a diverse set of real-valued signals that are derived from separate band signals that make up the input signal. The derived real signals are passed through configurable non-linear transformations, which may be adapted during operation, and which may be efficiently implemented using lookup tables. The outputs of the non-linear transformations serve as gain terms for a set of complex signals, which are functions of the input, and which are summed to compute the pre-distorted signal. A small set of the complex signals and derived real signals may be selected for a particular system to match the classes of non-linearities exhibited by the system, thereby providing further computational savings, and reducing complexity of adapting the pre-distortion through adapting of the non-linear transformations.

The method includes: forming a plurality of polysilicon patterns on a substrate, the plurality of polysilicon patterns including a first polysilicon pattern for forming the PIN-type diode and a second polysilicon pattern for forming the transistor, each polysilicon pattern including a first sub-region, a second sub-region, and a third sub-region between the first sub-region and the second sub-region; using a first doping process to dope the first sub-region of the first polysilicon pattern and the first sub-region and the second sub-region of the second polysilicon pattern with one of P-type ions and N-type ions respectively; and using a second doping process to dope the second sub-region of the first polysilicon pattern with the other of P-type ions and N-type ions.
US10644039B2 Wiring layer and manufacturing method therefor
To provide a miniaturized semiconductor device with low power consumption. A method for manufacturing a wiring layer includes the following steps: forming a second insulator over a first insulator; forming a third insulator over the second insulator; forming an opening in the third insulator so that it reaches the second insulator; forming a first conductor over the third insulator and in the opening; forming a second conductor over the first conductor; and after forming the second conductor, performing polishing treatment to remove portions of the first and second conductors above a top surface of the third insulator. An end of the first conductor is at a level lower than or equal to the top level of the opening. The top surface of the second conductor is at a level lower than or equal to that of the end of the first conductor.
US10644038B2 Array substrate, display panel, and display device thereof
An array substrate, a display panel, and a display device are provided. The array substrate includes a display region and a non-display region surrounding the display region. The array substrate also includes a plurality of gate lines. The plurality of gate lines include a plurality of regular gate lines and at least one irregular gate line. The plurality of regular gate lines are disposed in the display region and extended along a first direction. The at least one irregular gate line includes at least one first trace portion and a second trace portion electrically connected to each other. The at least one first trace portion has a same line width as a regular gate line of the plurality of regular gate lines, and the second trace portion has a line width smaller than the at least one first trace portion.
