Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tunable capacitors exhibit variations in capacitance values due to manufacturing process factors, leading to performance inconsistencies that are difficult to control, especially in applications requiring precise tuning settings, which often results in increased production costs or constrained device configurations.
Innovation Solution
A method and system for calibrating tunable components, such as capacitors, by measuring device responses, storing calibration codes in non-volatile memory, and adjusting tuning settings to achieve desired responses, thereby compensating for manufacturing variations and achieving more precise performance without increasing costs or constraining device configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manufacturing process control is tightened to reduce capacitance variation, then manufacturing precision is improved, but production cost increases
Solution Approach 1:
The patent applies preliminary action by measuring and characterizing each capacitor's actual capacitance values during manufacturing, storing these measurements in lookup tables. This pre-characterization allows the system to compensate for manufacturing variations through software calibration rather than requiring tight manufacturing control, thereby reducing production costs while maintaining precision.
2Manufacturing precision
If component design is modified to reduce sensitivity to process variation, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent changes parameters by storing multiple lookup tables with different capacitance values corresponding to various tuning settings. The system dynamically selects and applies the appropriate lookup table based on the desired tuning setting, allowing precise compensation for manufacturing variations without constraining device configurations or increasing physical complexity.
3Measurement precision
If tuning settings are adjusted to compensate for manufacturing variation, then measurement precision is improved, but productivity decreases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing compensation values in lookup tables during manufacturing. This eliminates the need for time-consuming real-time calibration procedures, as the system can directly apply pre-determined correction values during operation, thereby maintaining high tuning precision without sacrificing productivity.

AI summary
Systems, devices, and methods for adjusting tuning settings of tunable components, such as tunable capacitors, can be configured for calibrating a tunable component. Specifically, the systems, devices and methods can measure a device response for one or more inputs to a tunable component, store a calibration code in a non-volatile memory that characterizes the device response of the tunable component, and adjust a tuning setting of the tunable component based on the calibration code to achieve a desired response of the tunable component.
