Engineering Contradiction Analysis
1Loss of energy
If the wiring lines of the switched-capacitor circuit are used to connect capacitors, then the circuit can be implemented, but resistance losses occur leading to deteriorated output characteristics
Solution Approach 1:
The patent applies local quality by differentiating the placement positions of different capacitors in the circuit. The first capacitor is positioned closer to the integrated circuit than the second capacitor, creating non-uniform spatial distribution that optimizes electrical performance by minimizing resistance losses in critical signal paths.
2Reliability
If capacitors are arranged in the switched-capacitor circuit, then voltage generation is enabled, but wiring line resistance causes performance degradation
Solution Approach 1:
The patent implements preliminary action by pre-positioning the first capacitor closer to the integrated circuit before the circuit operates. This strategic placement is determined in advance to minimize the length of wiring lines and reduce resistance losses, ensuring optimal voltage generation performance from the start.

AI summary
A tracker module includes a module laminate; an integrated circuit; and a first capacitor and a second capacitor arranged in or on the module laminate. The integrated circuit includes at least one switch in a switched-capacitor circuit that generates a plurality of discrete voltages. The at least one switch in the switched-capacitor circuit is connected to at least one switch in a supply modulator that generates an output voltage by selectively switching among the plurality of discrete voltages based on a control signal. The first capacitor is a first flying capacitor of the switched-capacitor circuit, and the second capacitor is a smoothing capacitor of the switched-capacitor circuit. Moreover, in a plan view of the module laminate, the first capacitor is arranged closer to the at least one integrated circuit than the second capacitor.
