Implementations disclosed describe techniques and systems for calibrating parameters of a radio frequency power amplifier. The disclosed techniques include, among other things, identifying an initial power amplifier (PA) parameter set of a radio frequency (RF) module. A plurality of candidate PA parameter sets is generated. A set of error values for each of the plurality of candidate PA parameter sets is determined. A subset of the plurality of candidate PA parameter sets is identified. Each error value of the set of error values of each candidate parameter set in the subset satisfies an error threshold. A final PA parameter set is stored.

A method for rendering data of a three-dimensional image adapted to an eye position and a display system are provided. The method is used to render the three-dimensional image to be displayed in a three-dimensional space. In the method, a three-dimensional image data used to describe the three-dimensional image is obtained. The eye position of a user is detected. The ray-tracing information between the eye position and each lens unit of a multi-optical element module forms a region of visibility (RoV) that may cover a portion of the three-dimensional image in the three-dimensional space. When coordinating the physical characteristics of a display panel and the multi-optical element module, a plurality of elemental images can be obtained. The elemental images form an integral image that records the three-dimensional image data adapted to the eye position, and the integral image is used to reconstruct the three-dimensional image.

A stereoscopic image display device is provided and includes a flat panel display unit, a lens array unit, and a spacer unit. The flat panel display unit has a display surface. The lens array unit includes at least one condenser lens, which is disposed on a side of the display surface. The spacer unit is disposed between the display surface and the condenser lens, such that the lens array unit and the flat panel display unit are spaced apart from each other. In a light field system of the stereoscopic image display device, an object distance between the display surface of the flat panel display unit and the condenser lens of the lens array unit is configured to enable an absolute value of a central depth plane (CDP) of the stereoscopic image display device in the light field system to be between 1 mm and 200 mm.

An asymmetric differential inductor includes first and second conductive wirings spirally disposed on a substrate having a first input terminal, a second input terminal, a ground terminal, and a central conductive wiring. The central conductive wiring has a central contact connecting the ground terminal and a central end away from the ground terminal. The first conductive wiring extends across the central conductive wiring and has a first contact connecting the first input terminal and a first end connecting the central end. The second conductive wiring extends across the central conductive wiring and interlaces with the first conductive wiring and has a second contact connecting the second input terminal and a second end connecting the central end. Corresponding portions of wiring sections of the first and second conductive wirings at opposite sides of the central conductive wiring are asymmetrical to one another to thereby save substrate space and facilitate circuit layout.

Asymmetric differential inductor

A symmetric differential inductor structure includes first, second, third and fourth spiral conductive wirings disposed in four quadrants of a substrate, respectively. Further, a fifth conductive wiring connects the first and fourth spiral conductive wirings, and a sixth conductive wiring connects the second and third spiral conductive wirings. The first and second spiral conductive wirings are symmetric but not intersected with one another, and the third and fourth spiral conductive wirings are symmetric but not intersected with one another. Therefore, the invention attains full geometric symmetry to avoid using conductive wirings that occupy a large area of the substrate as in the prior art and to thereby increase the product profit and yield.
